It seems to me rather, that you are using a definition of "capitalism" that is distinct from and perhaps at odds with how other people are using the term.

The definition you're using seems to be clearly a far-left, anti-capitalism interpretation which has essentially inverted goals/motivations with side-effects/externalities compared to what a pro-capitalist, market-oriented type of person would suggest.

Basically, you're suggesting that regulatory capture is a goal of "capitalism" and while most people would say that's an anti-capitalist failure of government.

Everyone agrees regulatory capture is bad, so maybe we could all work together to fix that badness regardless of abstract differences of opinion.
