I don't know why people think direct democracy is at all good. What evidence is there that the majority know what's best for them?

It just sounds nice to say things like "government for the people by the people". In reality, I see no reason why everyone should have the right to vote. To be honest, I'm not even sure if I think I personally should have the right to vote.

Think of it like this: Do you think a body studying quantum theory would or should let anyone join? Or do you think they should only let people who have expertise in quantum theory? Similarly, why would anyone be allowed to vote? Why the hell do I even want a government run by me when I personally don't understand economics or civics to a level worth any real note?
