We've had a solution to this for a long time in various programs - let the user tell the application how much they know. By default, settings are extremely limited, but you can change settings to "advanced" or "expert", and more options/settings become available.

There is no reason this couldn't work for permissions as well; beginners get the system locked down pretty well, whereas advanced users get a more open system they can do more with, at the expense of potential foot-guns)

(As a side note, we could probably make a plane that had this principle applied as well. With autopilot where it is today, we could easily make a commercial plane that grandma could fly under most circumstances - you just need that real pilot and extra controls for when things go wrong.)
