If representative government is intrinsically flawed, why don’t we replace it instead of supplementing it?

We have over 200 years of experience with representative government, much of it successful. Bringing the citizen lawmaking to the federal government will permit our representatives to take back a good deal of the power that has devolved to bureaucracy. They will be in a position to be more responsive to the People with respect to the day-to-day operations of government. This legislative task is called "oversight," of which our representatives presently do very little due to a lack of time.
