I think you misreprepresent history. The people calling themselves "libertarian socialists" in the early part of the 20th century were not "on the other side of the aisle" exactly, they were almost all anti-capitalist. And if you're talking about the literal U.S. major political parties, there was not the "Republicans==conservative/right and Democrats==liberal/left" association then, what literal congressional "side of the aisle" did not have the left/right liberal/conservative association it does now, party politics were different. And "libertarian" didn't mean then what it does now in the U.S. either.
But yes, a variety of politics are possible, not just two, and Heinlein certainly had his own odd one, agreed.
In Starship Troopers, of course, everyone gets a kind of UBI I think, but only those who serve in the military have the political franchise. That was a fairly early work of his, and he definitely kept getting weirder from there.
