I'm a left anarchist, Libertarians are close to right anarchists. Democrats are vile hateful things that literally only show up as lesser evils when contrasted with republicans.
I'd say I'm a libertarian socialist, with a slight aversy to decentralizing too much, but that's mostly from a 'if it's not broken, don't fix it' perspective.
Dutch government has been decentralizing healthcare from national to town level, and it's created a mess, budget deficiencies on city budgets, inequality based on living area, and tons of overhead costs (now ever city needs a well paid healthcare manager, and team of insurance lobbyists, instead of just once at national level) and bureaucratic clogging of the apparatus, because city governments weren't prepared for the job (as a result, waiting lists for special care / psychiatric care / youth care have started taking lives).
So yeah, public works that function effectively and efficiently at national level should not be decentralized.
https://en.wikipedia.org/wiki/Libertarian_socialismLibertarianism has been giving libertarianism a bad name lately though, so I've gotten into the habit of telling people who ask me what political philosophy I adhere, that I'm a Cynic.
Sadly, cynicism has been giving Cynicism a bad name lately, and living naked in a barrel and telling the king to sod off is illegal nowadays. And cold. The Netherlands isn't Athens, you know. But at least people don't think I'm a Libertarian.
