because it does make you a terrible artist
quality is a part of art, yeah, but content is also a big part of it. would the mona lisa be as popular of a painting as it is today if she was topless and had stuffting richard nipples?
content has little to no influence.
the statue of david depicts him bare ass naked yet he's standing tall in a public display art museum and being appreciated by billions from many countries.
there are paintings all around the world of naked angel children with snakees. my mother owned 5 of them and hung them proudly in her home. as did millions of other americans.
old Renascence artwork depicts many nude paintings, such as the painting of the naked man touching finger tips with God. he has a snake. all of this artwork is still appreciated today.
your logic is invalid.
