In line with the bulk of what you say. Your post is smart and well documented, and I really love the hong kong analogy.
my only caveat: when you say «The Blockchain in the context of the money use, Bitcoin, appears to be a form of money, but it is not.» Either I did not understand what you mean or I disagree with that: if you say that bitcoin is not real money but just text sent around, one could argue the same for bank notes. The value of a currency is what a group believes it is. Tomorrow, a dollar not can be worth nothing if nobody believes in its value.
