Why even ban them? In this context "insecure" seems to mean "vulnerable to theft". If somebody wants to buy something that's easy to steal, that's their issue.
If people inadvertently buy easy to steal vehicles that's an issue, and maybe there should be labeling, or or a testing initiative, or maybe it's just a temporary blip that will work itself out as independent parties pick up testing.
If it's known which vehicles are prone to theft the market should work everything else out. Insurance can price it in, and buyers can factor it in to their purchasing decisions.
