Takeaway message, use more dark arts or better frame arguments.

Try using the outside view: of all the people who conclude something similar to the above when their ideas are poorly received here, what fraction are actually right? If this fraction is low, definitely explore other hypotheses. Frankly, I find yet another plan for more rational governance without any any attempt at an implementation mechanism to be quite boring and not worth spending many clock cycles on.

I also wanted to challenge people's thinking by getting them to consider if they actually believe in democracy.

You do realize that there are people here that don't believe in democracy, right? These people are unlikely to be impressed by schemes to fix democracy with more democracy.
