Can you imagine any event that would lead Starfleet to require mandatory Starfleet service from the youth of member worlds - say, 5 years and then you can remain or go do what you want?
Alternately, would a Federation member world enact mandatory Starfleet service for its own young people, in the hopes of correcting social problems, rebuilding their population (benefits of Starfleet education, physical training, mental discipline) etc?
