I had the same exact idea regarding delegation years ago, but I no longer have the requisite faith in humanity to agree with it.
How many of us are actually wise enough to delegate a vote, when we think ourselves wise and others foolish?
And how many of us are actually qualified to decide public policy, when we can barely manage our own affairs?
Just imagine what sort of absurd tyranny a vast mob of common humans could accomplish if the power were truly given to them.
It would be surreal.
( A minimal republic, and a system of full-on social darwinism, to me, appears to be ideal. )
