I think facebook has each user valued at about $200USD/year. A 2016 article from the Guardian puts it at $60/year... so I'm not sure which number to believe.

In my dreams, if the price point were low enough, like "the cost of two coffees per year" or something, and it wasn't irritating to pay it, there are plenty of people who want out of FB and could afford that.
When I started using privacy.com, I found it a lot easier to fund stuff because it was frictionless to generate a CC and drop it into a payment form automatically.
North American and European users are worth a lot more than users in developing countries.
