True, and a free market doesn't provide judges and courts to enforce contracts, money is not coined and regulated from some online vendomat, lots of things governments do that free markets need and can't do. Same the other way around too (like creating jobs and wealth). We need to agree that markets need governments and that our debate is not whether governments serve and support markets but how.
A free market does require courts to enforce contracts, and it also requires laws against fraud and coercion.
Free markets and anarcho-capitalism are not the same thing at all.
Free markets could handle the issue of currency just fine. It’s government requiring payment of taxes in a specific currency which has locked us into using the US dollar, but it doesn’t need to be that way.
Markets do not at all need governments to coin money or to regulate the price thereof. I believe that, left to its own devices, a free market would choose silver and gold as superior forms of money.
They would definitely not choose a currency which is constantly debased and which could be created in endless amounts at a keystroke by a party accountable to no one for its actions.
