The people of California desired a license plate reader system for certain purposes, but not others. The Tenth Amendment permits them to do so.

RBAC for example. Not everyone has and should have the same kind of access. Even at my dayjob I can imagine use cases where it would be inappropriate to provide certain data even to some coworker internally.

This is a Chesterton’s fence situation. If you can’t identify the problem that this law solves then you aren’t qualified to remove it.

The law exists for a reason, I encourage you to imagine what that might be.
