For me, the angle is a bit different. I want privacy, but I also sense that the people who are really good at this (like Plantir) have so much proxy information available that individual steps to protect privacy are pretty much worthless.

To me, this is a problem that can only be solved at the government/regulatory level.

In principle, I agree with your point; in practice, I think the claims made my these surveillance/advertising companies are likely as overstated as Musk's last decade of self-driving that still can't take a vehicle all the way across the USA without supervision in response to a phone summons.

The evidence I have that causes me to believe them to be overstated, is how even Facebook has frequently shown me ads that inherently make errors about my gender, nationality, the country I live in, and the languages I speak, and those are things they should've been able to figure out with my name, GeoIP, and the occasional message I write.
