Established economies are difficult to change to something better. Too much is invested in the present system. Change evolves at best with directed evolution instead of revolution. Putting fire breaks and fire proof housing in established communities would be nearly impossible.
What might work is using new technologies for improved fire spotting and suppression. Fire resistant Tesla style solar roof panels to create energy self-sufficiency to reduce fire ignition sources in power transmission lines suc as the Paradise fire ought to be mandatory.
I wrote years ago about establishing a million goat army to eat brush and forest floor dead leaf layers as a practical way to reduce fire combustibles. Before humans lived in North America lightning was the only source of ignition. Today there are literally billions with drunks tossing cigarette butts out the window along with a cloud of additional sources. Maybe some d signer bug will eat Los Angeles foliage occasionally in the future.
Drones could be used for fire spotting and faster suppression response time. Desalinating sea water on a large scale could fill covered fire control water reserves. I would suggest building canals along the Mexican border to fill with seawater pumped uphill to the Continental divide with solar power. Let the water and be collected when it comes on sloped clear roofs from the locks numbering in the thousands. Freshwater would flow in pipelines east and west to bring water to deserts.
Getting fire breaks built across the west will be nearly impossible with established vested interests resisting. As global warming increases national desertification people will want more water and find less unless the make it themselves. Making home power production increase is part of the equation for satisfactory fire suppression.
A nation cannot afford to pay for reconstruction of costly homes for the prosperous lost because the rich sometimes are airheads on public safety concerns a priori.
