If we fixed prices for one thing, we'd have to do it for everything. In a world where resources aren't exactly infinite, that creates a huge problem; especially when you have to pay people who're producing this fixed-value commodity (because you need people for that) and you have to increase their wages to buy stuff that isn't fixed-value, like housing (since land is a limited, though abundant, resource).

There's infinite land in the universe, let's go get it (/s, but only kinda)
