Not when they’re funneled through states like Wyoming and Nevada which an enormous amount of them are… both have very good privacy laws protecting the owners identity. Often times there will be a local LLC which is owned by (at least one) separate out of state LLC in Nevada or Wyoming obfuscating who the true owners are. There’s a whole industry behind this.
It's actually not, because it's a non-issue. The privacy of a Wyoming LLC doesn't mean protection. Your name isn't on any of the public records documents, but a court order can still force the disclosure of the interested parties.
It’s only a non-issue only if you have legal standing and the wherewithal/funding to push through to discovery, which in this case is a really (in)convenient catch-22 if you’re a constituent who wants to institute reform.
The fourth estate, the one that we ostensibly trust to hold power to account, again very conveniently, does not generally have that standing, FOIA excepted.
Not everyone has to be rich to want/need privacy. Maybe you had threats against your life and dont want your house and vehicle to be traceable to your name. Maybe you disagree with the automated license plate reader/tracker and this is one of the only legal ways around that.
