Of course the state is made up of people, but those people operate inside a pre-existing system of property, law, coercion, and institutions. That system doesn’t change just because you swap officeholders. Under capitalism, the courts defend private property, the police protect capital, the media belongs to capital, and the economy is owned by capital. Anyone entering that structure is forced to govern within those limits. That’s why workers can vote forever and still remain exploited.

You keep saying “just put different people in charge,” but history shows what happens when elected governments seriously threaten capitalist ownership: capital flees, investment stops, media turns hostile, courts obstruct, and imperialist pressure mounts until the project is neutralized or overthrown. That’s not theory, that’s how bourgeois power has observably functioned from its inception . Liberal democracy allows rotation of managers, not transfer of class power.

You’re also reversing cause and effect. Democracy doesn’t shape class relations, class relations shape democracy. As long as private ownership of production exists, the state exists to defend it. That’s why bourgeois democracy always resolves crises in favor of capital. It’s structurally designed to.

Real change only begins when exploitative property relations are abolished and the old coercive apparatus is broken and rebuilt to serve the working masses. That’s when democracy stops being a shell and becomes material, because the people control production, not just ballots.

I beg you to please read Lenin, and Chairman Mao you don't understand what you're talking about and they have far more extensive writing on this than I can fit into a debate with you on a message board.
