I think a lot of her YouTube ranting indirectly admits this, or at least her mindset. When she moans about trolls she really does see the only option being for them to shut up. At no point does she accept that it's not nice, but it is part of the job that she chooses to do. If she was a cashier and said she's sick of rude customers, she'd simply be told to move jobs. But she doesn't see that as an option at all. So she either has delusional ideas that she's too famous for a job like that (you're no Adele, Nicki), or she knows YouTube is a gravy train. I think both.
And I completely agree with you on her being unemployable anyway - she seems to have that mindset that some who grow up coddled with money do, she flits around part-time jobs with whatever hobby takes her interest at the time. She does a bit of make up (badly), writes a book (badly), but hasn't worked a full day in her life. I don't think she's capable of it, she has no idea what it is like to have to engage at work for set hours.
