There are definitely 10X teams in that sense. Two problems:
(1) Very few corporate compensation programs are team-oriented; managers are structurally forced to reward/punish individuals, not teams. In many cases there is even some sort of forced distribution that requires the manager to punish someone on the team regardless of performance. This makes it counterproductive to attempt to construct a uniformly high-quality team in the first place.
(2) The organizational friction encountered by a 10X team is the same as for a 10X developer, only much larger in scope, thus more expensive and visible. A 10X developer might want to write a bunch of unit tests; a 10X team might want to swap out the entire CI/CD system and reorganize their relationship with product management.
