Almost every couple manage to arrange their wedding without any unusual rules and demands. So most people seem to have taken your advice at heart. My advice to you is trying to make your argument without tired and boring insults such as "take a hard look at yourself". People have different opinions and perspectives, you can only accept that.

I've never made any strange rules for guests when I host, and I've politely declined the very rare cases when I've received such an invite. Because I know it's not about me.

You're free to dislike the request of the couple. I have no argument with that. People can be over the top. But I can't imagine skipping the wedding of someone I care about because I don't want to adhere to a simple request like not taking photos.
