While points 1 and 2 are indeed desirable, point 3 should be moot given we have a constitutional right to privacy and freedom from unreasonable search and seizures.
The combination of ubiquitous scanners, poor data controls on commercially owned date, and law enforcement access without proper warrants compounds to a situation that for many rational people would fail the test of being fair play under the Fourth Amendment. For similar reasons, for example, it has been held by the Supreme Court that installing a GPS tracker on a vehicle and monitoring it long-term without a warrant is a 4A violation (US v Jones). Similar cases have held that warrants are needed for cellphone location tracking.

I personally think this is a mistake and is a first-order reason we have this problem, and would prefer the matter to stop there rather than rely on ethics. (Relying on ethics brought us pollution in rivers, PFAS and Perc in the ground, and so on.)
