Yeah, but those who are sanctioned by governments have much more incentive to use Bitcoin, so the fact that most don't use it is not important, what is important is its existence as an option.
It's not really an option. The hard (and VERY low) cap on transaction volume is a joke. If you think a Bitcoin is actually an option for actual banking for actual people (not just the current set of a few thousand gamblers), you are delusional. The current financial system DOES process more transactions in a millisecond than Bitcoin CAN in a week.
