I own the originals for many roms I have. Ones I don't own I tend to delete after I beat the game, or if I really like it I buy a legitimate copy when I happen to find one. You are correct that not many people care about owning real copies. It's just piracy, like downloading music or movies. Almost nobody cares and the ones that do, only care on the surface. There are much bigger problems in the world than an illegal download. Also I own Pokemon Emerald and Fire Red, despite not owning a DS nor have I ever played non-hacked versions before.
