In the 21st century only a system based on direct democracy can function. And thanks to technology, it can attain levels of perfection that were unimaginable. Imagine electoral promises recorded in a blockchain, and then the votes. Accountability.

But for such a system to work well, power must be distributed as locally as possible. Avoiding centralization also largely avoids corruption.

It's a system, not an ideology, because ideologies cannot function anymore, not with the "richness" of diversity we have in most nations. But you would find neighborhoods and towns with impressive ethnic concentrations, and the direct democracy would allow a people to make as many rules as makes sense, for themselves, within the greater framework.

So in a sense, it's a system that allows for ideologies, to each (group) their own.
