So do nothing is what you are advocating for?
Don't break your leg jumping to imaginary conclusions.
To recap, since you're having trouble following along.
1. You can't compel private landowners to mitigate fire risk, that is unless you want to trash private property rights.
2. Even if mitigation steps have been taken, they may, or may not work under extreme conditions for all kinds of reasons. As an example: I don't give a shit how much defensible space you have if a landowner chooses to have cedar shakes on their roof, or stack their firewood under their deck. I don't know how much fire you've fought in your life, but I did it from 1987-1994 and its not uncommon for fires to spot 1/4 plus miles ahead of the fire front. If one of those embers lands on a cedar shake roof...your house is burnt toast.
3. Since you can't compel your neighbors to mitigate fire risk, your property could be at risk because of what they don't do.
4. Fire behavior has become more and more extreme over time...more red flag days, stronger winds, extreme drought...making previous mitigation efforts all but worthless.
Deny it all you want, but I'm not in denial, seeing it first hand. Fire seasons are longer and longer, more intense, fire doing things that we haven't seen in the past. Way more construction in WUI, often with piss poor zoning and layout. Too many things to list them all.
Clear enough?
