I disagree. This is necessary but not sufficient to describe a conspiracy. Conspiracies imply collusion, or some form of plan.

Patriarchy as it is commonly understood in feminist circles is more nuanced than your straw-man. It's bottom-up, not top-down. You'd have to stretch the definition of "conspiracy" awfully far to cover an emergent property of a set of principles and societal norms.
