Arbitrary rules are better than no rules.

Of course the concept of fair price is made up. The money itself is made up, it's just pieces of paper with serial numbers. Does that mean we all just have to bend down to every trickery ever invented by the rent seekers to extract value while bringing none? No, fuck rent seekers, their parasitic behavior ought to be punished by arbitrary rules.

Money is not sacred. The market is not sacred. It is supposed to serve people. Once it stops serving people, it ought to be changed.

Well I think more people would agree with my attempt at a definition than "no such thing as a "fair" price", but I don't have a survey handy.
