That's why Limited Government is the way. If the government is weak and starved for cash, it will lack the ability to influence markets or prop up monopolies. There will always be some interference, but with really small government, you can get close to a "free market".
Agreed. Free market capitalism is something that will never be achieved. It’s pretty clear from centuries of history that as soon as one guy figures out how to get a bit ahead, everybody else starts to feel entitled to figure out how to get themselves a bit of what that guy has. Some people cheat or con, some are actually willing to work for it, others go into government and take it at the point of a gun, in the name of “the people”.
