This is an important point - developers have a tendency to focus on our individual performance rather than the performance of the entire organization. In my experience, while individual performance goes down for some with pair/mob programming, both quality and velocity go up for the whole organization.

And it goes without saying that we developers love our freedom because it means we can work at our own pace. Often I find when I'm pairing all day I'm putting in way more focused time than when I am soloing.

Not my experience at all. All you need is one toxic/incompetent/stubborn developer to be part of your group and everything slows down to a crawl. Removing developers from a team can dramatically increase the productivity of the team.
