Which determines price.....but if you install a price control, then supply/demand is eliminated. That is why you install a price control (MAP), because the current supply/demand situation has become unfavorable to you, for whatever reason. So, you attack the market.
That is totally okay, but don't then turn around and talk about supporting markets or using the "your money" point or hit on the Federal Reserve. They are in essence doing the same exact thing Spyderco is doing with the MAP, and which you are trying to defend. Regulation is regulation. The only way around it is black markets, which in this case is essentially Ebay or r/knifeswap. Long live Ebay!
