I disagree, there's no meaningful distinction whatsoever.

Why? If it were any other issue, no one would care about the distinction. If Allegan County, Michigan banned firearms, people would still claim it's an infringement of 2nd Amendment rights, even though it's just "concerned parents asking relevant institutions at the local level" and not necessarily a state/federal law. But when that same exact county bans books and/or libraries instead, suddenly it "doesn't count" for some reason?
