You can't meaningfully regulate for specific things before they exist for one. Trying to do so prematurely would result in nonsense that would only hold us all back. Not to mention matters of enforcibility.

Facial recognition's biggest abuses are from the fox watching the hen-house. "Common sense" would lead to such absurdities like banning using it on cops because "everybody knows criminals could use it to track them" while using it on every protester because "they might be terrorists" despite both known truths being complete bullshit.
