I'm not clear on whether it's actually a good idea, but if Bryan Caplan's arguments are the best available, it's definitely a horrible idea. He sidesteps all the potential problems without addressing them, or in some cases draws analogies that, when actually considered properly, indicate that it would be a bad idea.
I particularly like how he manages to switch between deontology and consequentialism in the same argument.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
