Not only should “gouging” be “legal,” but in fact welcomed. Gouging ensures a supply of a good even when supplies are constrained. For example, gouging of event tickets ensures that you can get a ticket at a moment’s notice. Although the price is high would you prefer high price and ticket vs. no ticket? Rising prices due to increased demand is the market-natural rationing system. If prices stay low, then no one cuts back and the good is quickly consumed. High prices incentivize conservation so a given supply last longer and is available to those that desperately have a need of it.
