Another problem with this is, if a doctor or an airplane maker screws up, I can abandon them and go for a replacement immediately. With politicians I'm pretty much stuck until the ignorant masses change their minds.
That's why I'm a believer in highly federated, localized "competitive government".
So am I. We only differ in scale.
I'll assume you mean to say all the way down to the individual level. As it were, discrete and indivisible at that point. Notwithstanding, we can delegate our protections to any collective we choose, as long as we can come and go at will (or at least according to our contract).
What most people never get, is we can't delegate other people's rights; that would be enslavement. Actually, I better be careful. One can't denounce his own rights either. It's an oxymoron. To willingly give one's rights up would be to do so freely. You couldn't enslave yourself either.
