You still need someone to run the studio and manage projects, that didn't happen on its own. If anything, Solo and Resistance are proof that Star Wars doesn't just print money off of name recognition alone.
Again, hate her or love her, Lucasfilm has done quite well under her management.
I also feel like people think heading Lucasfilm is her first gig, or even the first time she has worked with the company. Her resume is ridiculous.
