I'm pretty sure that those 3 were specifically designed to not be default-able to prevent people unaware of the powers they give random people. Imagine you're someone who doesn't read instructions (i.e. most people in this game) and then you whine and complain when people start stealing your builds, destroying your entire map, deleting scripts, and kicking players simply because you either didn't read what the permissions do, or accidentally enabled them and forgot to turn them off.
