I found this post hard to follow. It would be more intelligible if you gave a clearer explanation of what problem you are trying to solve. Why exactly is it bad to have the same people look for problems and fix them? Why is it bad to have a legislature that can revise and amend statutes during the voting process?

I also don't really understand what sort of comment or feedback you are expecting here. Do you want us to discuss whether this lottery-and-many-committees structure is in general a good idea? Do you want us to critique through the details of your scheme?

The scheme seems to have certain advantages and certain disadvantages. I am personally quite skeptical; I would need to see lottery-based administration work at a small scale before I tried it on anything larger than a village.

What sort of evidence would convince you that this was, on balance, a bad idea?
