And what I'm saying is that "caused" is a weasel word when things have more than one cause. To have a fire you need a spark, air and fuel. The air is there all the time. The fuel is there whenever there hasn't been a spark recently. And power lines aren't the only source of sparks. Once the fuel is there and accumulating, you're playing roulette to see if you're going to have a smaller fire now or a bigger fire later. There is no option for "never have a fire again" in those areas, and the second option isn't inherently better than the first one.
