I feel any game is possible to pirate given enough resources. However, point taken, there's definitely a certain drop off point where the resources required to do it aren't very likely to be marshaled when it becomes sufficiently prohibitive. It's preferable to a company trying to squeeze all the profits possible out of their games, but certainly not for preserving gaming history many years later when profits aren't much of a factor.
