Actually, the argument voids itself, since when you say "considering that reality, as you perceive it, could easily be a delusion" you cannot know if that is a real perception of the perception of reality, or a delusion of the perception of the perception of reality. The question is how far do you want this argument to go. Because the perception of the perception of the perception of the perception of reality could be a delusion as well, which would still make reality real. So let's just say that it's a highly flawed argument.
