I'm sure there is a market for that functionality. But is it something you'd really want? Would there be limits on how much you could request from someone? Would bots spam everyone on earth requesting $50? Do you have to maintain a list of who can and cannot request money from you? It just seems like there would be a lot of headaches with that system.

Why? Are there limits on accessing your own bank accounts IRL?

No. Facebook would not allow that to happen. They control their user base with a tight fist when it affects their own revenue (user privacy less so).

Why bother? Yes it could be uncool behaviour to request money from people, especially if the request had some social pressure around it.

But people can (and do) already behave in uncool ways on Facebook and the world goes on.

The potential revenue from being a money pipe would motivate Facebook to effectively deal with all of these problems.

I believe Vivaldi has both of these features. Unfortunately, it seems a little bit more resource intensive than Chrome or Firefox on admittedly low-mid tier hardware.
