Allie is not "earning far more by actually working far less." That implies that working less causes her to make more money. Rather, she's earning more by charging more, and she was able to do that because she had complementary skills that she didn't know to market until price experimentation attracted a different kind of customer. As a side effect, her higher hourly rate gives her the freedom of working less.

Perhaps there could be a market for prostitutes who don't have sex very often, if there were a way for prospective clients to verify this. But that's not Allie's business strategy.
