> I have no problem with Sony not offering DRM free versions of games that I can still download and play with the store. But if that goes away -> you must give me a path to local ownership.

I'm pretty sure that Sony and others would work their way around such legislation. E.g. spin-off shell "studios" that would be the legal game sellers, and when the time comes to sunset a batch of games, these "studios" would magically go bankrupt and cease to exist.

Then the onus would again put on the commuinity to break any encryption or otherwise reverse-engineer and preserve the games so they remain playable for legal owners. And the top-level companies would still be able to salvage and own the game franchise rights, so they would still be able to harass the game preservation community.

I don't think there's any workaround to stop this kind of cheating, other than mandating that (a) all DRM-protected or service-bound content needs to be submitted to an escrow organization (Library of Congress?) in a form that can be used to reproduce it locally, and (b) all submitted content is released to the public after X years.
