When people say direct democracy, they think everything should be voted on etc. ie. a pure direct democracy. This is not something feasible.
But for example Switzerland gives her people a right to vote on specific issues and many other ways to change the country's laws by people. Which is not a pure direct democracy, but has many tools that allow for a direct democracy.
A pure form of direct democracy would just result on a tyranny of the majority.
You know now that you mention it the idea I have for my own token would allow users to tweak something like interest rates directly with governance votes... lol... so perhaps I'm just being a massive contrarian these days just for the sake of disagreement.
