An oligarchy of elected experts is precisely what representative democracy is. Giving every decision directly to the voters is not something you see in any democracy today. We elect people to make these decisions on our behalf.
Hopefully experts in lawmaking. Of course you’re right that we as an electorate do terrible job of electing good lawmakers, but that’s on us, not the lawmakers. You’re absolutely right that this system sucks because of this. In fact, it’s the worst system of government in the world, except for all the others.
You think it is more important that the right (in your opinion) decision is made than the decision the electorate prefers is made.
This is actually a general argument in favour of rule by an oligarchy of experts rather than democracy.
