The only point I’m trying to make is that asserting these entities are private is false and leads to false conclusions. This is true.
The reason I didn’t address the government issue first is because the relationship between government and corporate is a lot more complicated than that, and the conversation almost always gets cut short by the assumption that corporations are private.
I also just finished explaining how the government does influence credit scores. If you’re so focused on this point, why did you ignore that?
