direct democracy is the only way

[lucy]

Because even in my small country of 5 mill people you cannot have a vote with all 5 mill anytime the smallest thing has to be decided.

And who exactly would be interested in voting on the smallest thing? That's simply not necessary. I can tell you what would happen if you tried to have vote on every chickenshit proposal: After a while almost nobody would bother to go to vote.
It's relatively easy to implement elements of direct democracy: You restrict it to elections, new or altered laws and projects that cost at least a certain amount of money and of course also everything that affects the constitution. There can also be an element of referendum, i.e. a law is only put to a public vote if a certain number of people demand it.

Works pretty well around here and has absolutely nothing whatsoever to do with the complexity of a society. I'm pretty sure Switzerland isn't that much more simple than say, England or Germany or Ireland. At least last time I've been abroad I didn't feel much like a tribal cavewoman.
