Why should we avoid it? Oh, I know a few arguments and they're compelling in abstract but are inevitably just arguments towards a reshuffling of who or what has power. Power over another, however you want to define it, is inherent in hierarchical structures, and I am sorry to say but hierarchies - that is, rankings of entities - are one of the most fundamental aspects of all known existence. How many electrons do you have?

I get where you're coming from. We should avoid concentration of power in human societies because this always (at least so far) leads to abuse of that power.

However, reality exists.
