In my mind the morality behind Bitcoin is simple.

For centuries mankind has been threatened by governments of all stripe whether they're communist, capitalist or monarchies to pay taxes, every one of them has used violence against the people to assert their power, now with Bitcoin they will have no choice but to work with us instead or they won't get any money at all. I guess it's kind of like when you finally get to move out of your parents house, in the end no matter what threats etc. they might use against you afterwards it means absolutely nothing because you've finally gained independence.
