Surge pricing is Good, but there are also valid laws against Price Gouging during and before an emergency.
And, yet, during an emergency there should be extremely higher prices so that the people who most need a scarce commodity can get it (yeah, I know, if they can afford it).
We had a severe gasoline shortage in Nashville a few years ago, I mean severe. Most stations had no gasoline. Some started charging exorbitant amounts. Good. See, I didn't need gasoline so - being a good citizen - I quit driving. My wife and I work from home so we didn't need to drive. We went to the store, but that was it. Other people, though, were talking about finding a station that still had gas and filling up so that they wouldn't be left without. They didn't need it, just wanted it.
I'd rather see the ambulances and such have enough gas that they can still run - even if they have to pay double or triple for it. That's what a market is for. If you force everybody to keep their prices down during those times then all that happens is people will buy even if they don't really need.
