If you give it some thought, it becomes obvious that since any name is used in many public settings, society/state has a legitimate case to prevent offensive naming. That is different from state literally creating an allowlist. The huge middleground is benign names that are in no way offensive but still require you to get an approval from the state. I think this is an overreach, ymmv

In order to lighten the administrative burden that occurs when society/state has a legitimate case to prevent offensive naming, society is likely to create an approve list.

Denmark did use to have "These and only these names" and they were written into the law (yes, there are pages and pages of Danish legislation that are just names), but now any non-offensive name is okay, and for administrative purposes, an "approved"-list is kept for easy reference to things that have already been, well, approved.
