Actually it would be even harder to achieve high precision with rotating tools.
AgX, the system I saw used rotary dies - they were trying to get out of the "flat die" method, which nevertheless was also used for automatic high production use. It's just that the advantages of the rotary system made it worthwhile; there is no risk of rubbing against machinery - with a rotary system, the moving film web can just "kiss" against the punch/die set which is moving at the same speed. Note that this was some years ago, when professional film production was probably at a peak.
