If you're fighting fires with water and trucks, your policy and planning is already a disaster. We didn't dramatically lower the loss from household fires by putting a fire truck on every block, we did it by building code changes, insurance pressure, and consumer product safety to reduce flammability of household materials. You won't stop California fires by dumping an extra billion into firefighting, but you might do it by mandating (by code and insurance) metal roofs/siding, making it take less than a decade to get approval for controlled burns, and a dozen other long term policy changes that have been suggested and mostly ignored by Californians for decades.
Luckily, if you don't do anything to mitigate your home's fire risk in California, the state will still insure you and pay for it via a tax on everyone whose risk is low enough to get private insurance. That surely won't lead to problems down the road.
