If Eraser Head tried to erase Mineta's quirk, would he stop producing the purple balls or would it not affect him because it is technically a form of physical quirk?
Similar to what is stated here, Shota Aizawa's quirk do not work on Mutation-class quirk and Mineta's quirk is classified as one.
So no, Mineta cannot stop producing purple balls even if Eraser Head used his quirk.
