Isn't that not just a technocracy? I actually think a system like that would make a lot of sense, but I still believe the population should have the power to veto a law that they don't want.
As for the brexit vote being undemocratic, I see your point, but I don't think just because the people were uninformed that means the referendum was undemocratic. First of all, I don't think most MEPs who voted for the copyright reform were any more informed, on average. I also think it should ultimately be up to the population of a democratic system to decide things, even if they don't understand the situation entirely. That's the point of democracy.
There's a Youtube video kicking around of someone (I forget who) going round Europarl asking MEPs if they'd actually read Articles 11 and 13.
The most common answer, by a country mile, was "no".
We elect representatives to read these things and make a reasoned decision on our behalf. Not to do the political equivalent of putting on a blindfold and throwing a dart, hoping to score a bulls-eye.
Manipulating people and having them vote without all the facts on the table and then denying them that vote after the facts were on the table is not democracy.
I think that too, IF they take the time to become experts in the matter of the law they don't want.
And who decides who is an expert on what?
For example I am for a "democracy of experts" system, in which any decision must be voted exclusively by those who have expertise on the matter the vote is about.
From my point of view the Brexit vote is totally not-democratic because it put an absurdly complex decision on a big part of the population which has not even remotely the competence to decide on the matter.
As you see it is not all white or black.
