There is nothing that Valve could change about this with the current way games are licensed.
All your Steam account is is a collection of lifetime leasing contracts between you and the seller. Steam already forces third parties to give you liftime access even if the game is pulled from the store page, but that contract gets voided once one of the two parties ceases to exist, be it the buyer or the studio that sells the game.
Legally binding the games to your account instead of you also isn’t possible since in most countries you either have to be a real person or a registered entity to form contracts.
You are definetly in a bubble, even if its a pretty big one. Owning a pc is pretty much a prerequisite for going into comp-science or working in IT.
Out of all the 30 odd people I know of at my workplace, one other apart from me has a gaming pc, and two others have consoles. The rest doesn’t play any games at all.
