Well, "compelling" isn't a good organizational principle. I'm not saying we should evict grandma at the first hint of insurance prices rising. There could absolutely be compensation for property, negotiated buyouts and moving costs, or other good policies.

For better or worse, markets are the clearest signals we have in a hugely messy world. That shouldn't prevent us from doing the best thing available, but the world is not inherently fair and safe, and it's not possible for it to be perfectly fair and safe with our current technology and psychology.
