I have anecdata about victims of domestic violence using these tools. There are even entire guides for how to do so (eg Michael Bazzell's Extreme Privacy). It's hard to tell how many people are doing this when the entire purpose of doing it is to obfuscate who you are.

I know a mildly famous family that got some attention from stalkers in the past and now owns their house under a shell company.

Unless the stalkers had access to law enforcement resources that doesn’t seem relevant.

They are using, specifically, an economically inactive shell company to protect themselves from people who wish them harm.

As far as I know there is nothing special in the corporate structure that would make it difficult for law enforcement to find, the point is to stay out of public records.

So it's not relevant - this law doesn't make the shell company information public.

Stalkers can _BE_ law enforcement. Just google "cop stalking ex".

Yeah I already said exactly this in another thread. But again, unless anonymous shell companies are the way people are avoiding that, it's not relevant for this discussion, and much more effectively addressed in other ways.
