Its a rational and sensible choice, consciously or unconsciously. The individual team member with the strongest focus on sociopath skills in a team will reap all the benefit from team members who mistakenly instead focus on productive skills/activities. Therefore any productive team members ALWAYS benefit from doing the absolute minimum, letting the "team" concept fail, and implementing their own solution. There are two optimum success modes, one where the whole team never reaps any personal success (psuedo-anonymous closed ranks at least from external view or its simply not a sociopath-compatible success oriented task) or where the whole team has no one with any sociopath skills at all or at least perfectly matched sociopath skills (good luck). Maybe the TLDR is you can try to create a team, but the member with the best social skills will make the other members destroy it, or at least convert it from a "team" to "a group of people with a semi-common goal not working together at all".
The other interpretation is nothing paralyzes as well as a separation between responsibility and authority, and nothing defines that separation quite like a team. Fundamentally nothing ever gets done by a group, its always one individual where the rubber meets the road, so all you really need is that one individual, the rest of the team was excess baggage other than maybe providing peer pressure on the lone actual worker.
