Butterfly Labs took pre-orders and everyone was rightly skeptical. Then they shipped (extraordinary evidence). Same for Bitcoin Magazine. Does BitInstant or Bit-Pay, or MtGox or Bitcoinica or Bitstamp offer returns to investors? [edit: i mean crazy returns to most any investor]. Hell, does Silk Road? No, because those are all businesses actually generating profit.
So when pirate returns everyone's principle and interest, we'll have our extra ordinary evidence.
