Would you be happy if regulators mandated that airplane control systems can only sample their input at most every second?

HFT systems look a lot like feedback driven control loops. Mandating a minimum resolution would be ridiculous.

If what you're sampling and responding to is noise, then yes, it's pointless.

If what you're sampling and responding to is noise, and the responses themselves generate self-perpetuating expanding feedbacks, it's worse than useless: it's actively harmful.
