one of the things the public hates more than price increases during a shortage is higher taxes any time
Maybe? Though in this case what we’re taxing is the disliked activity—price increases during a shortage. So possibly this would be popular, like taxes on alcohol, tobacco, or gambling?

The main good bit of market pricing this would miss is the demand reduction and reallocation caused by the higher prices. I might be willing to buy 100lb of ice at $1/lb but only 10lb of ice at $5/lb: it’s easier for me to just dump a bunch of ice into my fridge, but if I prioritize and put the important stuff into a cooler I can make do with much less. If the government is subsidizing suppliers to keep the price at the pre-disaster rate I don’t have this incentive to ice more efficiently.

True. The main thing the “tax a price increase” misses is that it mutes the supply incentive effects of the price increase. I’d need to understand the elasticities of the two (including the pre-supply incentives for some goods: a decision to store more than current demand BEFORE the emergency gets paid DURING) to really make a recommendation, and it’d likely be specific enough to time and place and product and reason for emergency that “don’t get involved at a one-size-fits-all level” is the only thing I really support.
