What solution do you propose for private businesses? Having cameras is sensible, if not a must. People are abusive, burglars break in, staff steal, etc.

You can install cameras in a way that you only film the parts relevant for potential break ins. In my country this is demanded by law. So not directing cameras on public streets or other properties.

Aside from that, camera necessity isn't real, affordable cameras for mass deployment are perhaps not recent, but there certainly were other ways in the past to handle crime.

I don't have a solution (and would be mindful any 'solution' could be unreasonably burdensome, unenforceable, or have unintended consequences). I just point out that the past couple of decades have seen a dramatic change how easy it is for people to be spied on, often in sensitive environments and unbeknown to them.
