If you support banning sports betting because it's a zero-sum game that is generally -EV for non-professionals in aggregate, and if short-term trading of stocks is also zero-sum and -EV for non-professionals in aggregate, then do you support also banning short-term stock trading for non-professionals?

I don’t know exactly what the right regulation would look like to restrict this specific kind of activity, but I don’t have a problem, in principle, with such regulation.
