The rules of parlimentary democracy primarily seems to be a way to reduce the whims of a great number of people to a small number of people in a room talking. The issue is that building consensus or even giving everyone a fair chance to air their views in a group of 20+ people is EXHAUSTING. Have you ever been to any local politics groups where there are more than about 20 in a room? a meeting to decide what to have for lunch can take 3+ hours. It has its perks too, and its a lot faster when everyone gets to know each other and feels that they are known, then they dont have to repeatedly restate their points every time.
I guess what im saying is its a system very much built around the analog practicalities of speaking with physical people in a physical room. I think we can do better with the internet
