Well put. I've found this to be a common and annoying class of flawed discourse: comparing artificial problems of greater severity or potential to that of related but lesser natural and intrinsic problems as a justification for it being acceptable... you can apply the same reasoning to justify making everything as badly as possible, it's nonsense.
