No. Why? Because even if I paid $1/mo, many other people wouldn't. As such, Facebook's value goes down - without their contact information, postings, photos, etc. Facebook has no value. So, even if one is willing to pay for Facebook, by charging money Facebook would eliminate the reason why one would pay for it - namely that almost everyone is on it and creating lots of content you want on it. That's part of the reason that it's so hard to monetize a site like Facebook - the value is being created by the users, not by you. You're just a venue. Should you want to change them for their own content, they'll just move to another venue. It's somewhat like trying to charge teenagers for loitering in your store. Sure, they're using your place as a venue and it costs money, but some definitely won't pay and as some start leaving, the crowd will follow even if a part of the group would be willing to pay for the venue.
