The internet is for whoever wants to send bits to each other and is willing to pay for transit to do it. The WWW might be for end users, though that seems less obvious by the day.

Right. The RFC is attempting to clarify the IETF's official position. The IETF is not the internet police, and can't make other actors obey.

We can make our own internet though - with blackhack and jookers.

what you write is excactly the problem the RFC tries to address. And not only for http but for the whole internet protocol family.
