To paraphrase this article - 'if we trust Sarah to vote as we wish on the environment, and Frank to vote as we intend on Finance', what I don't understand is how would delegative democracy work when it comes to working out the environmental budgets for that year?
That's a good point. I think it's hard to definitively know the best way to resolve issues like this without an actual platform to test it on.
One point that I wasn't able to fit into the article is that this idea isn't a homerun. There are lots of difficult things to figure out. I just think that it's hard to find a problem more deserving of solving, and right now we have our best minds solving the problem of how to spy on people better instead.
