Fully in support of this, but it will never happen, at least not for digital purchases, for a simple economic reason: the internet enables far too efficient a market and it'd wreck businesses with the first sale doctrine. One game sold by the publisher would then be constantly resold by endusers with an ever decreasing price to the point that you could probably buy most of any game for a couple of bucks a year or so after release. The reason this doesn't already happen with physical copies is because there's tedium + cost involved in the transfer, and they also create a motivation to collect. It's somehow enjoyable see a shelf full of games, music, movies, or whatever else.

More realistic would be improving copyright law. I think it'd be reasonable to state that copyright lasts 20 years from the first 'transfer' (sell, licensing, etc) of a creation. 20 years is long enough to fully monetize, but also short enough to really enable some interesting acceleration/derivation in society. For instance just about now XBox 360 games would be coming out of copyright protection. That seems perfectly reasonable, especially in the era of LLMs where 'sidestepping' copyright is going to be increasingly trivial anyhow.
