> draw funds by taxing homeowners, specifically, and limiting payouts by fire risk, capping at a mean replacement cost, not per-house

This almost seems designed to maximise fury. You're still taxing low-risk homeowners to pay for high-risk damages. And when a catastrophe hits, you aren't paying enough to rebuild (or avoid bankruptcy, in which case you're just routing taxpayer funds to creditors). Add to that you've branded it a tax increase it's almost something the GOP would run as a false flag against a Democrat.
