Just off the top of my head, the way I see it, the main fault in almost kind of utopianism is it has to be pretty big to survive. And as soon as it gets pretty big, you get some bad apples in it. And as soon as you get some bad apples in it, you've gotta make laws against the bad apple-ness.
Well, you know, just as an example, the FDA was formed to protect us collectively against unscrupulous "bad apple" distributors of meat, milk, veggies, etc. Just as an example.
Yeah, some laws are specious, but a lot of licensing laws are borne of things like that --a proper reaction to "bad-appleness."
This is also not to say that everything is just hunky-dory with today's burden of over-regulation, but the way to handle this is to de-elect the bounders through normal processes.
Or by limiting all legislative sessions to 2 days a year and knock off all the perks that were voted in by the aforesaid bounders themselves.
