Your point neglects the reality that most machines, no matter how much you wish it weren't true, will just never be collectibles. And besides, even if one simply defines something's value to a collector by it's rarity, then diminishing the supply by destroying surplus equipment, one automatically increases the value of the remainder of the supply. In that case, you should applaud the needless destruction of Macs in other people's collections. But that is a poor way to define a collector's item's value.
