There are many explanations for this, of course, but the root is probably a fear that rulers have some kind of magic. We fear that without them we'd crash and burn. After all, we've been trained in precisely that for a hundred generations. Rationally we know it isn't true, but emotionally we're not entirely convinced.
So today I'd like to make an important point: That we'll be better off – massively better off – without them. The nagging fear that we're missing something is simply false. The better we get away from rulership, the better off we'll be.
I like crunching the numbers on these things because the failure of rulership is hidden in plain sight, little recognized. Digging into numbers the rulers themselves publish can help break through the blockage.
