That’s pretty much only because the idealized form of democracy in the West is a representative one, i.e. the people vote in a representative when a certain period of time passes and hope they don’t cave in to foreign interests/bribes.
In a direct democracy, the people have a direct say in government policy and can make their interests known via regular votes and meetings. I’m not going to pretend like it’s a flawless form of democracy, but it’s definitely harder for bad actors to push their agenda if citizens can directly push back against that without any red tape getting in the way. Unfortunately even consideration of it is extremely rare in the world though.
