You purchase lifetime access to the game. Lifetime being, just as with warranty, for the lifetime of the game.
For live service games the problem isn't that your access will be revoked at some point. That's a given. Rather, it's about the proposition being unclear during the purchasing decision. This is the big problem, it's impossible for people to know what they're buying.

And such the analogue exists with warranty. And it's one of the solutions. Create a period of guaranteed service.
