The praxeologists often feel to me like they are not so much arguing with people as they are speaking a different language. The result is confusion and frustration. This certainly happens with Voiskuil. 

I think there are useful things to be gleaned from this mode of thinking, but it quickly gets bonkers if not grounded in reality.

Yet the rational economic theory on which is based,  and the theorem itself, explicitly rejects empiricism.

This seems to be a major weakness of the Austrians.  They are so against empiricism that they reject a lot of useful methods of gaining knowledge.  IMO, there shouldn't be such a conflict between empiricism and deductive reasoning

The idea is a reasonable empirical theory on the evolution of the concept of money, but invalid as a rational theorem to distinguish money from non-money

Again, a very frustrating dichotomy.  It's totally rational how the value of Bitcoin arose from predictions regarding the future, or even how someone simply wanted some (for 

 reason) and was willing to trade some goods for it.

It seems to me like people think there are a lot of dichotomies in economics which don't actually exist that hard among practicing economists.
