first of all, Mises’ Regression Theorem does not say anything about significant minorities, or too small a population
I read books about money by Menger, Mises, Hayek, Rothbard, Huelsmann, and Bagus. Also books by non-austrians.
Have you ever come across the phrase “money”? Mises uses it in his regression theorem over and over. Since it is an advanced book, he expects you to remember, when reading Page 405. what he wrote ten pages earlier on Page 395.
To help those who don’t have a copy of the book in front of them, we’ll quote it right here:
A medium of exchange which is commonly used as such is called money.
The notion of money is vague, as its definition refers to the vague term
“commonly used.” There are borderline cases in which it cannot be decided
whether a medium of exchange is or is not “commonly” used and should be
called money.
Our friend Wikipedia also insists that a medium of exchange, to deserve the name, be “widely used”.
Since you say you read Rothbard, you will surely have met these words from Man, Economy, and State:
A commodity that comes into general use as a medium of ex-
change is defined as being a money. It is evident that, whereas
the concept of a “medium of exchange” is a precise one, and
indirect exchange can be distinctly separated from direct ex-
change, the concept of “money” is a less precise one. The point
at which a medium of exchange comes into “common” or “gen-
eral” use is not strictly definable, and whether or not a medium
is a money can be decided only by historical inquiry and the
judgment of the historian.
Now, call me suspicious, but I fear that the next ridiculous defense of bitcoin will be that 25 geeks in their mothers’ basement who use bitcoin for geek cred, and certainly the number of people using bitcoin right now, constitutes “wide” “general” and “common” use. After all, the term is admittedly vague, and up to the judgement of the historian, meaning anybody at all who wants to. I will not bother to argue about that. You have every right to your opinion, however foolish and misinformed, about the meaning of those words. To me, “wide”, “general”, and “common” means you can buy most everything for sale in Walmarts or in a Sears catalogue with a bitcoin, which is hardly the case.
