I think it sets off the misogyny alarms, but I think the point remains: someone with a quality that could conceivably be used to meet a financial need opens up a valid criticism. We'd say the same if it were a developer asking for money, or a homeless person panhandling when they appear physically fit. I think there's a resistance when it's based on appearance, not skill, but I think there's plenty of models who would take exception to the idea that there isn't work and skill involved.
