>Why then don't you utilize 215-9 ??

Are you asking why I don't just use GFCI breakers for everything?

Two major disadvantages are that one has to go to the panel to test or reset them.

Considering how rarely people test a GFCI when it's right there, I can't imagine them going to the panel to test them.

My habit with rarely used GFCI outlets is to leave them tripped when not in use. That reminds me or the next person to test before using.

I don't get what you are saying about economics either. But yes, a GFCI outlet is usually cheaper than a GFCI breaker.
