This thread talks about the "ability" to do harm. You don't need to own a car in order to park a car in the middle of a highway. You can rent one for instance.
What I meant is just that you don't need to be a billionaire to cause harm. Sure, you can find an example of somebody who has absolutely zero money, and cannot physically do no harm to anybody (e.g. because locked up in a prison or something), but that's besides the point.
I don't.
