I'd like to remind that IP protection does not solely exist to benefit authors. It exists to benefit the society as a whole. That is, not only the writers and actors, but also the readers and viewers. The original post, if you take a look, is about an obvious disbalance of the benefits the IP holders of old games receive vs the lost benefit of the society from preserving these games. Many games are works of art, on par with books an movies, a part of society's cultural heritage.

Unlike physical property, "intellectual property" requires quotes, and does not enjoy a constitutional protection, all for a good reason.

My proposal has a few benefits that, to my mind, outweigh the shortcomings.

* It is very simple. There's no room for any shenanigans, small print, etc.

* It is very uniform. It applies to every kind of IP (of the same class) equally. Again, no room or need for small print.

* It has a large enough free grace period, longer than the peak periods when most movies make the large box offices, most books have the first 2-3 successful reprints, most games have initial sales + DLC sales, etc. For most folks, nothing changes, because their revenues from a particular IP go to zero or near-zero by the end of the grace period.

* It's guaranteed to terminate the IP protection sooner or later, and most of the time, sooner. No demand curve stays exponential forever; the fee stays exponential as long as it takes.

* It does not depend on any accounting. No box office numbers to smear, no audience sizes to inflate. No matter how much you earn, you can pay for the protection as long as you care to afford it.

* It protects the most valuable / profitable IP preferentially. If something is really really huge, and people keep asking the authors to shut up, take their money, and produce moar, that thing can stay protected for longer. When most people stop caring enough, it becomes pointlessly costly to keep protecting it. This benefits the few that care though, the librarians and archivists of the world, and the new creators who now can build freely on top of the things that went to public domain.

So no, the small author just does not have to pay anything, small authors are just protected for 10 years for free, and may buy half a decade of protection cheaply if they care. But after that, they should admit that this particular cow is not worth milking forever.
