Because playing to an audience is different than playing with friends. It's a different experience, and if you want to be successful it requires a different attitude and way of playing. It requires a commitment to keeping to dates and schedules that goes beyond any home game.
And because if you're looking to make money from someone else's performance, it's impolite at the very least to expect them to perform for free.
Out of curiosity - do you have any personal experience with broadcasting with this or is it just speculation? My nephew did it for a little while, but then he also did it with a bunch of improv buddies who were used to performing.
Personally I might feel a little awkward at first but I would assume it would fade after a short period. Then again, I'm sure it would be different for everyone, I've given speeches in front of 100+ people and it didn't really bother me.
