Earlier quoted context omitted.
Yes, I don't think replicated data structures are the problem. Look at single player video games, cannot get more ideal for local-first. Still you need a launcher and internet connection.
No you don't. There are plenty of games you can buy and go into the wilderness and play just fine offline. Just because game developers WANT you to be online so they can get data doesn't mean you NEED to be online.
There are currently tens of thousands of games that are unplayable due to requiring pinging to a network/patch server which long ago was deprecated.
Forsaking patch requirements, just as many games are no longer playable due to incompatibility/abandoned OS, codebase, gamebreaking bugs.
In both of these scenarios, my "lifetime license" is no longer usable through no action of my own, and breaks the lifetime license agreement. I shouldn't need to be into IT to understand how to keep a game I bought 5 years ago playable.
The solution to this "problem" for user, as offered by the corporate investment firms in control, is to offer rolling subscriptions that "keep your license alive", for some reason. Rather than properly charge for a service at time of purchase.
TLDR: Why move the goal posts further in favor of tech/IT/Videogame Investment firms?
