Fires can start from natural causes too. It's ignorant to say that this sort of disaster can be prevented by fixing behaviour, and it's a special form of hubris to think that you can "unstupid" everyone. This is the worst plan you can have. Relying on all individuals not doing something stupid for a long time is a lost cause, just look at the state of covid in the US. There are people literally throwing parties or sending their kids to school while they know that they have covid.
