Why don't we install a knob that we can turn that effectively limits trading to X seconds precision?

One day we may decide to turn that knob from the millisecond range to 1 second and see what happens. If it's bad, we can always turn the knob back.

> If it's bad, we can always turn the knob back. Sure, but by then maybe some people or organizations have made/lost millions. So we can't realistically experiment with that (even though I would absolutely love to)

If a businessmodel is questionable from a societal viewpoint, then they shouldn't be surprised that some regulation hits them. See for instance Airbnb, where the businessmodel has become impossible in many cities already.

it would make more sense to first get rid of the penny rule.
