Sony deletes more movies from the accounts of people who ‘bought’ them

If I didn't pirate movies and games and Windows and apps when I was young, I probably wouldn't be in a position to pay for multiple streaming and Xbox subscription now.

Why would that model not work if you got to keep one copy of the current catalog? Consider the existing failure mode of the fractured streaming market: The user signs up for Netflix for one month, binge watches everything they're not caught up on, cancels, signs up for Disney+ the next month, does the same, repeat for each service. They only subscribe for one month out of the year but still get to watch everything.

What would change if they had to sign up for a year a time, but as a result got permanent access to everything that was in the catalog that year? Would people sign up once and then cancel forever? Of course not, because then they wouldn't get any newer content, which is what the services are supposed to be getting paid for anyway. Copyright is supposed to expire; why do we need a business model that relies on renting years-old works that under any sensible system would already be in the public domain?

> And yet obviously the subscribers individually spend far less in many cases than it would cost them to buy permanent copies of everything they'd listened to and watched.

Which is to say, they should offer bulk discounts where you get the whole catalog for a fixed amount, but then what's the problem?

It's not that people could resell them, because if you bought them all at once then you would only be able to resell them all together (can you currently resell individual tracks from an LP?), and then many people would want to keep some of them and thereby keep all of them.

> I don't really buy the other argument you're making either. With digital works there isn't much reason for a "second hand" market where copies would be significantly cheaper than a "new" copy direct from the supplier.

Sure there is. If the price was the same then most people would prefer to support the creators. On top of that there is the same reason most ordinary people buy electronics from Walmart or Costco instead of eBay or Craigslist. The product may be exactly the same, but Some Guy is a lot more likely to take your money and not deliver anything and then people will pay a premium to get it from a trusted source.

> When people used to trade used works on physical media there was a degree of degradation in those media that justified a price reduction.

This argument has always been nonsense because you were always allowed to make a backup copy of something you bought and then transfer that with the original if you sold it. Far from the copyright holder having a right to the degradation, the customer has a right to undo it.

> Why would someone who had bought a copy of the latest summer blockbuster sell it for 30% of its original purchase price if it's a flawless digital reproduction identical to a new one?

Because they don't want it anymore but need to provide some discount or people would just go to the original source. The amount of the discount would depend on supply and demand -- if lots of people buy it but then it sucks and they all want to get rid of it, the resale price is low, but maybe that's what ought to happen then.

> Naturally this shifts the dynamics in the market and the price of buying a true permanent copy that can legally be sold on afterwards would tend to increase because of this effect.

Except that it also increases the value of the product by that amount because the buyer can do that. If the price of a rental would have been $2 and the price of a copy would have to be $10 but you can resell it for $8, what do you care? If you want it temporarily then buy it and resell it; if you want to keep it forever then at least you'd then have the option to do that whereas right now there are things where buying a permanent copy isn't even available.

> Meanwhile the library services I mentioned above work on almost the opposite basis and it tends to push the price per work accessed down because the subscribers aren't effectively subsidising other people who are enjoying identical works to themselves but without paying the original source anything to access those works.

And a buy in bulk plan would still work that way. You would pay for a lot of assorted works at once (e.g. everything in the Netflix catalog that year) for a much lower price per work and then have the option to keep them or resell them all together. Keeping them permanently would naturally be more expensive, but not as expensive as buying them all individually, and either way then it's up to you.

> I think there is demonstrably room enough in a world of billions of people with access to orders of magnitude more content than any of us could experience even once in our lifetimes for multiple economic models.

The general problem here is that copyright is a monopoly, which as a general rule is bad but we're trying to get something good out of it by providing some incentive to create works. But to prevent a monopoly from being abused it needs to have a lot of limitations on it, which is supposed to be fair use, first sale, antitrust prohibitions on tying, etc.

If you just let them do whatever they want then look what happens -- you pay a monthly fee forever to never own anything, things disappear at random, owning a copy isn't even an available option, the service dictates what kind of device you can use to watch it which in turn causes antitrust problems for playback devices, etc. It shouldn't be like that.

> Clearly market forces haven't always sorted that one out effectively and some sort of adjustment is warranted. But I'm also wary of relying on some form of government regulation that distorts the market and potentially excludes arrangements that everyone actually involved might find worthwhile.

The source of the problem is that "government regulation that distorts the market" is already there in copyright itself. It's trying to do something useful, but you can't have it both ways. The thing the market uses to keep things in check is competition. Once the government issues a monopoly, the monopolist has to be strictly limited in what they can do or they'll turn into autocratic robber barons.
