In my younger days I thought direct democracy was unworkable, but now I realise that might have just been my brain conforming to the bourgeois representative government status quo.
Obviously we easily have the tech to do DD these days, everyone has a smart phone in their pocket, we could do it instantly and on the go. But how you could manage a planned economy that way I’m not sure.
I wrote out a whole thing but someone else's "liquid democracy" idea is basically it, but also abolishing the presidency and senate, and somehow overcoming the internet voting problem.
