In three denominations: Bad Beer, A Beer, and Good Beer. You need A Beer as the base currency (equal to “One job that I don’t mind spending an hour on anyway), obviously: and most people can agree on Good Beer, so that’s the higher denomination. But Bad Beer has a place in this, too: while there is a general consensus on Good Beer, there is not one on Bad Beer. SOMEBODY’S always going to be happy to drink it. So you would accept Bad BEERcoin as a kind of speculative currency: you might be able to trade it with somebody who would consider your Bad Beer to be Good Beer. Pretty elegant, if I do say so myself.
What’s that? “What’s it like to make economists scream in agony at the sheer ignorance of it all?” Kind of fun, really. Why do you ask?
PS: If this ever takes off, I want 1% of the gross. In Good BEERcoin.
