You can get privacy without paying by not using Facebook. Getting someone to host your pictures and provide you a platform to share them isn't a fundamental right.
By my privacy is so nobody can require me to pay for things with it. What point are you trying to make?
That's true.
So they can charge everyone and respect everyone's privacy rights, if they think that's the best business model for them.
What they're trying to get away with here is trading money for fundamental rights.
I can't legally pay Facebook to assassinate me, to take an extreme example.
