Liquidity may not be "the answer," but it can be an important answer in certain contexts. Because "store of value" is such an important feature for a currency, we need trust that the currency will retain its value. As we noted, the primary way of getting at this is via a market. To a certain degree, the larger and more liquid the market, the less we have to trust in the value. However, even with a small but liquid market we have the ability to easily and quickly get in and out.
