Exactly! Although it is only head-canon, I have used "The Ul'dahn" style of dancing to mean just that. As an entertainer in Ishgard it was the most important style in her repertoire, though in an incomplete and different form given the distance and isolation (one example: Ishgardian dancers of the style do not use finger cymbals, instead relying on bells sewn into their costumes to generate rhythmic percussion, they also do not have access to the exquisite body-jewelry that is a hallmark of the arts true practitioners in the Jewel of the Desert).
I view dancers who also moonlight as prostitutes the exception to the rule. Meaning, While I'm sure most dancers don't prostitute, there are those that do and they're the ones helping reinforce the ideal.
