Would operating outside the US and not accepting any US customers make you exempt from MSB rules and regulations?
U.S. MSB rules and U.S. regulations, yes. You may have similar rules and regulations for that jurisdiction however.
Yeah but at least you wouldn't have to deal with 50 States, FINCEN, the government, NSA, FBI, a culture of litigation etc. etc.
To put it another way - the States is probably the worse place on the planet to start a bitcoin business.
I'm still wondering why the Bitcoin Foundation is located in the States ....
