'Authorities' are to be feared and obeyed.
'Authorities' are the ones who know and have the power to prove that 'you do not know', to determine that 'you are wrong'.
'Authorities' 'represent' 'the law of the land', and have an army of weaponized soldiers who enforce the authorities' law, doing their overlord's bidding.
'Authorities' themselves are, of course, 'above the law'.
No 'good' person would ever want to be 'an authority', because on the one hand, you may be attacked by other 'authorities' who 'have more authority than you', and on the other hand, having 'authority' implies 'having a big ego', and therefore being a 'bad' person.
