No, but seriously. Consider it. I mean, the Superhappies are a highly egalitarian, collectivist, expansionist, technology-focused, peace- and compromise-loving culture with universalist ideals that they want to spread everywhere.

Aside from the different biology, that sounds like the Communist sci-fi utopias I've read of, like Banks' Culture and the Strugatsky brothers' Noon Universe. All three are a proper subset of "Near-Maximum Leftism" in my opinion. And I would hardly be terrified if offered to live in either one - or even a downgraded version of one, with a little Space Bureaucracy. Frankly, I wouldn't even mind a Space Brezhnev, as long as he behaved. I can name a dozen much worse (non-socialist) rulers than the real Brezhnev!

(Can you imagine tentacle sex being plagued by bureaucracy? "Sorry, comrade, you'll need a stamp before I can give you an orgasm, and the stamp window doesn't work today.")
