The problem still is with assholes and dumbasses, and a general lack of personal accountability/responsibility.
Banning stuff (guns, books, certain clothing, sharp metal objects, depictions of violence/sex, fun things that can lead to collateral damage, etc.) is just a cheap way of saying you don't expect people to teach personal responsibility and don't have resources to enforce personal accountability. People aren't owning up their actions' outcomes, acting innocent/ignorant, insisting there was no ill intent. Charging such people for negligence doesn't deter other dumbasses and assholes from making similar errors. People aren't trying to be proactive in trying to do what's righteous, either, such as out of love/gratitude for what is afforded to you.
Banning just seems to give justification to Karen-like habits--there's a bit of asshole, dumbass, and karen (including gossiping) in everyone, but there's people who DGAF about being rude/inappropriate due to being troubled/frustrated. The trouble/frustration simply could just be from their instinctual urge(s) being suppressed. Fireworks banned? Americans who have this urge will still bring them in around July 4th. Law enforcement knows this kind of stuff is low-tier-sh!t that isn't worth their attention, and that a lot of humans aren't wired to see fault in doing things that are like natural courses to them. It's like the COVID-19 spreaders, not caring if they infect many others until it affects them, and even then, they'll feel offended if they get blame, wanting to point to others to take some of the blame off them, while they conveniently fool themselves into forgetting they ever did anything bad/wrong.
Registration is controversial for being ineffective at meeting any of its intended goals, and not having the cost for its startup/setup and maintenance/operation (including issuance of tags) covered by anything like fees. All the money the DMV takes in wouldn't be enough to pay for its operation, even in rich states with a lot of cars (e.g. 2-4 cars per household).
