Why do people respect the queen and royalty?

I don't get it:, they haven't done anything special for us, they're just some random family we chose to look at as royalty and kiss their ass and worship them, for no other reason other than to worship someone, I guess to make life more fun or something, .

If I met her I would not treat her with respect, if she expect me to open a car door for her I'd jus say "do it yourself you old bitch"

Why are we respecting/worshipping some random family who done nothing for us, just because they was born with royal blood?
