The points made in this article remind me of how CD-ROM was adopted in the early nineties.
Once upon a time CD-ROM was new and with Windows for Workgroups you could share a given CD-ROM across a network. If you needed to install $SOFTWARE on machine B you could theoretically put the CD-ROM in machine A's drive and install from there. The person on machine A might even put the right disk in for you.
Given that CD-ROM drives cost a reasonable amount of money at the time and probably went at 3x speed, you would have a financial incentive to specify machine B without the CD-ROM, same with machine C and machine D. In so doing you could save enough money to buy machine E (or at least the monitor for it).
Nobody went down this route, in offices or in education. In education settings there were financial incentives to save money plus tech savvy staff on hand to make it work smoothly. There was no 'status' value in having the CD-ROM attached.
Everyone was okay about sharing the same printer but not the same CD-ROM drive.
You would not even need the CD-ROM as often as a printer in those days. The publishing industry was in its infancy and you only really had install media. Writeable media was a long way off. Surely it would have made sense to have your MS-Office install media or 'Encarta' available to all, on the network which was faster than the CD-ROM drives of the era?
Yet this never happened.
Instead every machine was specified with the CD-ROM. Disks were passed around much like floppies were. Nobody network-shared their CD-ROM drives. Yet all that was needed was a 'right click' and 'share'. The financial aspect in doing so was not a micro-payment in some alt-coin it was proper $$$ saved from not having to purchase another CD-ROM drive.
In time the $999 CD-ROM drives went to 4x and cost nearer $200, then they became 52x and cost nearer $100 to eventually become the $20 things bundled with every machine.
When writeable CD-ROMS and DVDs came along the storage space was vast compared to HDDs of the time yet still there was no network sharing of the things, everyone had their own disk in their own machine. Sure there were exceptions - network machines of the time - but these were the exceptions.
For the same reasons of capitalism and human nature I suspect that file-sharing-by-altcoin will fail. Moore's Law makes 'common sense' arguments for file sharing in a P2P way where you rent out your disk not make sense. Layer on top the fact that every alt-coin is a scam-coin and you know that P2P file-coins are only for the true believers.
