> “It’s worth what the market will pay for it”
Is absolutely true at the time it sells — it was worth that much for the former owner who now has that much cash from it. The bigger question is whether the next owner will get that much value from it. Sometimes there is no bigger sucker.
False. Suppose I possess a fungible asset, and that asset is selling on the market at a particular price. I can choose not to sell at that price, because it's worth more to me personally than the market price. Worth is subjective, price is not.
