> I'm not sure why you can park a car on the street for hours for free, but not, say, a picnictable with a BBQ, a folding tablesaw, a telescope, a pop-up bookstore, a film projector, and so on. You don't have to pay to do those other things either. You might not be able to because of safety reasons (e.g. a BBQ in some places) but the "for free" isn't relevant.
