That doesn't make any sense. Just because you want to sell an item for a certain price doesn't mean that you can. You are only talking about the supply side. If there is no demand, then it doesn't matter what the supply side is as nobody will buy them. Magic Roots have 4 uses. Nobody would use them to make Supercompost or to make a Crossbow String when they could make the same items with any of the lower roots. Nature Amulets are used and are still decently priced, but since people can only use one, the only people who would buy Magic Roots in bulk to make Nature Amulets are merchants. The Super Strong Anti-Poison can be very helpful in places such as DKs and since this is a consumable product, I'm sure serious DKers buy Magic Roots in bulk. Since I'm not a merchant and I don't DK, I can't tell you how strong the demand is, but it's obviously strong enough to keep the price as high as it is right now.
