Societal alienation makes for the best art and metal is no exception. Metalheads trying to exclude someone for being different (NSBM excepted) have completely missed the point of the entire genre.
Shout out to Genital Shame and Lust Hag making excellent Transwoman Black Metal!
Money. 6-axis isn’t cheap to run or maintain, especially at this scale with the desired precision. Add in the inherent issues of working with a variety of paint colors (especially aerosolized), subtract the ability to mask features from over spray. Their prices would have to make Warhammer look bargain bin in order to recoup the costs of the machine, maintenance and consumables.
