Couldn't the same be said of all professions in which some people earn a lot, such as acting, sports, singing, entertainment in general, and which are considered less “serious” than the professions of medical doctor and engineer?

One might say that, in theory, the well-earning actor or actress has to show some craft at least, but there are plenty of actors whose popularity comes only from their looks--my dog would act better than them.

A lot of the youngsters who'd decide to make money undressing themselves on OF will soon realize they might have the will, but they lack the market power.
