I think it's the fantasy of having complete autonomy, of being completely free in the sense of never having to do anything that you don't want to do[1]. At least, that's that's the aspect of it that resonates with me.
But it's only that -- a fantasy. Much like other things that we fantasize about, it's impossible as conceived because it dwells on the upsides and omits the downsides. Humans run in packs. We are social. It's that aspect that has always been the key to our ability to survive even in extremely bad circumstances.
The trade-off, looking purely from a selfish point of view, is that we give up some degree of autonomy in exchange for benefits that are so essential and fundamental that we are in great peril without them. We have better lives as part of a group than in isolation, despite being unable to do literally anything we want.
In that sense, it's a lot like some kinds of sexual fantasies. Hot as hell in your imagination, but not so great (or even possible) in reality.
