What’s an example? A gigantic mansion? You’d probably have to build that yourself, society likely can’t prop up everyone who wants a mansion, but if you build it yourself it would probably be seen as fine.
Again, Communism is an extremely democratic form of economic organization, so if the community deems it necessary to give you a mansion and has the Means to do so, then it can happen.
Communism is a far-future society, however, which is why Socialism is more known about and defined. Socialism however still has issues like having a state at all, so it’s not the end of history either.
