I wouldn't even go that far. They should charge the people for the rescuing, or if it's because of a stupid State law, the state should be billed.
Here in Arizona, we now have a law called the "stupid hiker law". Yes, that's really what it's called. The problem is that so many stupid people would go hiking in our desert mountain parks in or near the city of Phoenix, and would do so with little or no water, improper footwear, etc., and then would get in trouble and need a helicopter to come rescue them. Basically, it was a lot of either dumb students or other out-of-towners who would think it's cool to go "hiking" in flip-flops and a small water bottle, in the middle of the summer with 115-degree heat. When the hiking trail has an elevation of 1000 feet or more, the inevitable result is heatstroke and dehydration. So they made this law so that these morons get billed for the (very expensive) rescues they called in.
The same should go for anyone who needs to be rescued because they built too close to the water. That goes for tsunami victims too. We know all about tsunamis and their devastating effects now, so there's no excuse for any place to not be prepared for one.
