Any job “coach” seems ridiculous to me

So just any coach in any domain?

Coaching and guiding someone is a different skillset then leading and running a business. They’re basically a mentor/consultant for hire

If you can do it that well, then what the heck are you doing coaching?

This is crazy. We all do what we are best at or enjoy the most in one way or anothrr

Maybe they could run a business, 50 hours a week, but they’d prefer to help 5 businesses 6 hours a week each?

They may have a skillset where they can effectively produce the most marginal value in those fewer hours with each business. In that case it makes sense to repeat that multiple times rather than spending all your time immersed in one project
