RE: a system engineer’s perspective: what system is better than capitalist democracy?
You seem to be arguing that the corporate state is somehow an inevitable result of, or internal feature of, the market process and property rights when it is in complete opposition instead.
Society, the economy, and culture don't exist. There is no system. Only individuals exist. Only individuals reason, choose, and act. The process of voluntary interactions and exchanges between individuals creates the illusion of a system that isn't there. It's not a thing that can be engineered, and it's barely understood by anyone. The evidence of the consequences of attempting to plan and shape it surround us with wars, terrorism, and police states though.
Governments are gangs of thieves writ large. Taxation is theft. Imperialism is theft. Wars and genocides are mass murder. Political plunder rather than economic production are the goals of the people who call themselves "government." But governments don't exist, either. There are only individuals who choose coercion rather than cooperation. This is a principle in direct opposition to the market, not a correlary or attendant necessity of it. There is a history of illegitimate possession of property through such processes, but that is resolved through an understanding of property rights and homesteading as principles extending rationally from the understanding of the individual, not as a thing that is imposed arbitrarily.
