Yes. Freer Than Any Other Market.
No. Too Much Government Intervention.
Technically as free as a market can get, but subverts government intervention illegally so it's fuck all.
Neglecting it legality it is the true definition of a free market
Well when you think about it, The black market tends to form and grow only when the government intervenes, So yes the black market is the most free market there is. Of course by their very nature black markets are illegal, Which means breaking laws within the market is no big deal since you're breaking the law by simply selling or buying, And that can lead to other forms of violent crime.
I don't think we should give black people a separate market.
Actually it isn't really a free market because of (well government stopping the practices) but more than that there is no universal control of force. It is more anarchistic than free market. In a free market someone can't just kill their competition with guns.
A free market is a market free of government intervention. The black market being illegal is definitely evidence of the government intervening.
