The point is that what's common sense to an engineer is different than what's common sense for a lay person or an amateur. Their way of thinking is different. A lay person is not aware, doesn't know and can't mentally model the kind of power a microwave transformer can deliver: it's almost (almost!) an out of context problem for them. They just saw the pretty fractal wood burnings on tiktok and want to try themselves. And then they die[1] That's the point of all the scary warnings, caveats and reminders. They're there for not-engineer-minded folks, so that they don't hurt themselves or set their house on fire.
