I would very much prefer something clicks in their heads so they can see how horrible their acts are, then find an honest way of living and maybe even try and amend some of the harm they've done to humanity and the world.
Oh! And you can also add cops, that would be the population of Illinois, for a total of ~42.5 mill or the equivalent of the population of California and Utah combined.
I don't know mate, I wouldn't replace my electric tools–drills, grinders, saw... with gas ones. But these outdoors tools are a different kind of beast. I've only used an electric chainsaw and it was an absolute crap, maybe there are better ones but it was crappier than the smallest and shittiest gas chainsaws I've used, and a cord around you in that setting isn't great either.
