A lot of pre-built teams work that way because they have naturally developed the rapport required to operate so effectively. You can't force people to like each other and work well together. I'd hire a team in a heartbeat.
If by hire we mean "write a terminal contract to deliver a feature," sure, we certainly agree there. If by hire we mean "make full-time employees," it strikes me as significantly more work to ensure a team that comes in would like and be liked by the rest of my employees, and would work well together, than hiring individually.
Hire to me means the latter, so if we're crossing definitions unintentionally then I think we're probably aligned.
