We all bitch(atleast some of us do...

)...about the corruption in the hobby...the deceptive bidding practices of auction houses/ebay...the alteration of cards...the perceived inconsistency of TPGrading services.
And many of us long for a "cleaning up of the hobby"...I know I do!
What would be potential implications on our collections as a result of a "cleaning up of the hobby?"
Would our collections become worth less...more? Would more people enter the hobby? Would people leave?
Please discuss!
