You don't understand. Democracy doesn't exist because it's good. Democracy exists because there's nothing better. Every other system of power transferal leads to conflict and instability. The public at large is not smart and is easy manipulated. MP's, on the other hand, tend to be highly educated and not quite as easily manipulated. They spend most of their time studying and researching to make the best possible decisions. People do not, and cannot, commit to the same level of work. People making decisions would make worse decisions simply because it's impossible to fit an MP's schedule into every single person's schedule.
