It's hard to imagine shared single source competitive sports teams which are more engaging than having multiple teams with (nearly) independent player pools.
It does happen at schools, say, where the players for each team in P.E. class are picked at random, but fans get engaged with the team identity and the individual players, and team abilities depend in part on long-term shared practice.
It's hard to believe that the space programs of the 1960s would have been better had the Soviet and U.S. programs joined forces for a single space program; also, obviously neither space program was based on the direct market forces of capitalism.
The military is also not run under a capitalistic basis, and the concept of "single source" for a NATO or UN force is meaningless. It's even a stretch to say that a combined US Army/Navy/Marine operation is a "single source" given the inter-service rivalries. I'm not convinced that a single world government with its own military would be better.
