In general I have found that arguments are often not really about the points of an essay but about the definitions used, ie one person uses definition 1 and the other uses definition 2 and they just argue past each other.
For example if I say "Bitcoin is money", I don't think that statement is meaningful without defining what I mean by "money" and perhaps "bitcoin".
I don't think understanding the linked essay really depends on knowing what he means by "MoMT", he defines it just fine for us.
"Basically, MoMT tells us that money has anomalous value only because economic agents rationally speculate in it, whereas conventional thought (whether Austrian or orthodox) holds that money's price is explained primarily by its use in trade."
To me that's an interesting idea. Why not debate that? Instead all of the comments here are about a bunch of superficial bullshit (yours excluded).
