It's funny how every time free market tries to do something new which people consider useful enough to pay money for, somebody will scream for regulators to save us from it. Usually somebody that didn't build a scrap of honest value in their life.

Sure, you're going to say it's a problem of coordination. How about I give you another problem of coordination instead. In this world there are a lot of pretty complicated things, built by smart and learned people. Problem is, there is a supermajority of less smart and/or less learned people that sometimes get to decide what other people can or cannot do.

Usually, we can see that societies that let people mind their own business are a lot richer, happier, more civilized and more ethical than societies which tell people what they can do with their time, work and money. But there is still a problem of coordination that a majority of people still haven't internalized this meta-rule, so democracies tend to meddle a lot more than they should. But such is life.
