Let me quote from it:
You’re back to your old tricks where you attempt to obfuscate the difference between money and a medium of exchange.
And here you conflate the (broader) transaction costs with a subset of transaction costs (the size of the network, AKA “double coincidence of wants”).
But these are just auxiliary issues. The more fundamental one is that you lack a solid framework. I challenge you to formulate the regression theorem in up to five simple implications, like I did here: https://forum.freecapitalists.org/t/bitcoins-prove-mengerian-account-of-money-creation/21195/125.
