>Free market value is a common measure of fairness.

Free market value is a fantasy. No market is really free. No value is set by a free market.

If what you are saying is that in theory under certain completely fantastical assumptions that market value is fair and otherwise it's not, then yea, I agree.

I certainly agree that freedom isn't absolute: there are more of less degrees of competition in a market. However that doesn't preclude supply/demand setting values for things.
