It sounds a lot like you're proposing enshrining that sort of corporate serfdom in the law and prohibiting the situation where the customer actually owns their own property.

Nope. It was just an observation that I think most people are completely unaware of; or they accept it because the alternative of crappy phones from companies that do not care to keep them updated, or drop all kinds of trash all over them that cannot be removed, sucks so badly that a company can get away with what Apple does. You are voluntarily agreeing to that EULA. You don't in fact have to agree.
