> It also attracts people who can do it all - design, programming, animation, etc who become stars, and then wonder why they aren’t working for themselves.

This is why you promote to full partner all the time. The people who wonder why they aren't working for themselves should answer "I will have all the advantages of working for myself, plus the advantages of partners for the few places that matter". If you don't promote to partner you lose all the effort you put into training that person if you did you get someone who can help you once in a while.
