I would argue that we don't need new regulations, we need to enforce existing laws against fraud. It is fraudulent to sell something and then later disable ones access to the thing you sold them access to.
I would argue that it is likely fraudulent to sell with the intent to later reappropriate but separately illegal to actually do so. It’s some manner of theft or destruction of property.
Which is exactly why Sony claims not to "sell" you the game but only to license it.
Exactly, this is just application of property rights and enforcing existing consumer protection rights. You can’t tell someone they’re “buying” something if they don’t own it. Imagine someone doing that with house rentals or car leases, it would obviously be considered fraud.
