>"not just moving it from one place to another at a loss."
>By definition, unprofitable ventures will run out of capital and stop without government intervention.
in the context of this discussion it means :
"not just moving it from one place to another to generate personal profit at a somebody else's [usually wide public's] loss."
The government role is to prevent such profitable ventures which profit at the loss of the general public - free market isn't able to do so on its own.

>And the presence of the black market in all cultures shows us that it is universal that people want to trade freely.
presence of black market in the Soviet Union was showing universal people desire to smoke Marlboro and wear LEVI's jeans. Desire to trade freely would created the black market in bread as well, yet no such market existed. Such market exist in Zimbabwe though, where it shows universal people desire to eat.
