I've read several pages of this and noticed one thing: you seem to be arguing against the established form of capitalism based on the assumption that people are perfect.
Before you argue against that, let me explain: it all lies in this quote from you:

My idea is an integrated system of Capitalism and Communism where needs are provided by the state and entrepreneurial and entertainment industries are controlled by the market. It's not as flashy or lucrative as Capitalism, but its more stable and still supports progress.
Now, the problem here is that if your needs are provided by the state, nobody has any real reason to work harder than anyone else. Thus, everybody works to the minimum of their abilities, which actually deters progress. We're looking at an entrepreneurial and entertainment industry where the people are liable, so the obvious course of action is to get a menial government job so you won't be held liable for the costs of your actions. Nobody wants to be a brain surgeon if their living arrangements are the same as the trash collector. How are you going to get people into the medical professions?
Also, it takes money to, say, start up a new business. Given that your system is 'not as lucrative', when someone manages to get together the money for his new entrepreneurship, why is he going to try to start his business?
If your response to either question is "to get more money for what he wants", then your system is extremely close to the current form of capitalism, to the point where you may seem to be arguing against yourself. If your response is "for progress" or "for the betterment of mankind", then you are an idealist and don't understand how much people consider 'risk v. reward' before making a choice.
