Cash is a decentralized payment system, and we already know how to
achieve the same thing cryptographically if we are willing to assume
the presence of a bank (in fact we can achieve much more than Bitcoin
in that case).  The goal of Bitcoin was originally to eliminate banks
from the monetary system; decentralized payments are merely a
consequence of that.
