No worries

On the contrary, the difference between the Mafia and Coca-Cola is that Coke provides its product on the open market, without using violence to defend it's turf against Pepsi, and if it did, people would quickly stop buying Coke.
My contention is that advocating AnarchoCapitalism might just be the frustration of being unable to mount a revolution, because the U.S. Gov't is TOO rich and TOO powerful and TOO evil a company.
.
Perhaps this is more clear: the differences between Coca-Cola, the Mafia, and government are differences of degree, not qualitative differences.
Right people would stop buying Coca-Cola in that scenario. But if a gang started being as civil to its competitors as Coke is to Pepsi, then that gang would lose out fast. If the U.S. was as nice to England back in 1776, the U.S. would have lost out. So what is the underlying difference that makes it so?
because I know the US government to be too rich and too powerful for revolution to work,
I don't think so. If 300 million Americans (soldiers included) wanted a new constitution (and say canada and mexico and pakistan all hate america) they would get their revolution somehow. A better statement IMO is "the ratio of discontent with the US government to the US govt's power is currently too low for a revolution to work."
