Sorry, I don't understand what the problem is exactly.
There are plenty of other professions, like say music, surgery, law, athletics, performance and endurance sports, teaching and many more that require a person to go outside the normal hours and work to practice, to achieve any sign of mastery. The fact that these professions demand such an work setting is not because they inherently like to discriminate against a minority, but that standards of quality are held at such a high bar you inevitable have to work that way to make a living there.

There is fundamentally nothing wrong with it.
