Eh. I never proposed to disable comments on the whole site or like.
I proposed to give me and maybe some others such an option via markdown comment (could be hidden and not well documented.)
I admit many comments are valuable, when it comes to topics that assume some arguing. E.g. marking this particular post as comments: false would be silly :)
