I more or less agree with what you said. Yes, humans, as we know them right now, would not be able to pull something like this off. But I'm talking about the future, when humans will be more spiritualized beings, something like this may be possible.

Well, who knows what the future holds? Maybe, I dunno. I don't think we can change that much. And in some ways, I don't know if I want to. Competition (thus conflict) breeds innovation. A good enough world breeds complacency. Maybe there will be a better world, and I'm not advocating for a complete status quo. But there's a fine line between ambition, and crazy :p
Till then, our country didn't have its finest day today, so there's that, and it's not the last bad thing to happen. (I wrote a post about it, if you're interested. Sorry if the shilling is off base.) That's why I think that we should be careful going forward in any direction. As mentioned before, I think it's just as utopian, and potentially destructive, as communism, which also sounds great on paper, while reality shows the complete opposite :)
