That is, in fact, what a free market would encourage: If no one is buying at the price you're willing to sell it for, then you either lower your prices (if you need liquid assets NOW) or you hold on to it as an investment (in case someone will buy it for that price LATER). You of course have to balance the investment risk; if you're holding out for a price higher than anyone will ever pay, you've misvalued your non-liquid assets and you're not as wealthy as you think you are.
