This would be a much more compelling argument if it weren't for the fact that much of the spread of CWD can be traced back to game farms/shooting preserves. It's much deeper than merely not agreeing with shooting animals behind a high fence. If there was no threat to native wildlife populations, I couldn't care less about what "hunts" were sold.
There are many laws that limit what can be done on private land out of concern for wildlife populations.
And when cwd was spread what safeguards where put in place? I'm going to take a guess that there was little to none.
