That's exactly how a free market is supposed to operate: when there is a match between buyer and seller, both and seller get what they want. Whenever we hear talk of how "free markets failed," one of 3 things happened:
- the market which failed wasn't truly a free market;
- the person making the statement doesn't understand how free markets work; or
- both
Regulation can have a place in a truly free market, but the regulation needs to be in place to make sure the rights of both parties are respected and that neither party violates the rights of the other. Any other kind of regulation is an abridgement of the free market. Financial markets as we know them aren't free markets, and they are trying to suck cryptocurrency into their combined sphere of influence.
