Graders should just move to a system where it's slabbed as authentic or it's rejected as a fake. Buyers can then just decide on their own how much to pay for the condition/presentation of the card without the grading company opinion on that aspect.
You should then see the huge price gaps for condition fall and the card doctors much less motivated.
I know it's a completely different collecting mindset, but one that can be just as rewarding and enjoyable. In the PSA slabbed photo world, photo type is identified but no mention of condition, alterations, etc. and photo collectors do not put large premiums on condition. Just look at the most expensive photo (to my knowledge) that's sold thus far...
