Not included are all the efficiencies Bitcoin will introduce into the economy if it goes mainstream. A fully internationalized, frictionless division of labor will be an incredible boon to the economy. And there's so much more. I think a price target of $100 million, conservatively, is more realistic.

If Bitcoin goes big, it pretty much has to go whole hog. We are witnessing nothing less than a global transition from physical goods and trust-based money to an unimpeachable universal asset ledger. Anything else will look archaic by comparison, and the value added to the economy in the next 10 years will blow even these first 20 years of the modern Internet out of the water.
