Quote from the_cardfatherThis assumes there is actual "hoarding" going on. We know it happens on MTGO more often than in paper, and there may be 1-5 dealers with sufficient stocks of P3K and such, but most of these cards show up on eBay with decent regularity meaning they are still in circulation.
Well, the point of the matter doesn't assume hoarding is going on. The point is that certain card prices are protected by Wizards while others are not, and that this doesn't make a lot of sense. This fact then encourages hoarding of certain cards because you are nearly guaranteed to never lose value (until Magic dies).
