ELI5: Why would anyone want to ban using cameras to catch people who block intersections?

> "It doesn't hold a threat to anyone if there are signs but nobody is there," he said. "We either need cameras (not allowed by state law) or people to get some order. Some people don't learn until they get burned" with a ticket.

So why would California pass a law against such a sensible and useful policy?

Traffic cameras are often set up and maintained by 3rd party companies. The local police or municipality gets what's basically a kick-back to mandate them. Then, the company sets them up and gets most of the money (profit!) from the tickets.

They can also contribute to rear-end accidents as people slam on their brakes because they aren't sure when specifically they'll get a ticket for going through the intersection.

If there's a spot where someone is blocking an intersection that seems like a trivial matter for the police to fix. That tends to be cheaper and less extreme solution for what would likely be a short term problem.
