Standing in your defined fighting stance with guard up will do nothing to create or futher establish an advantage over someone who isn't even in a range to hurt you. In fact it would put you at a disadvantage given that now the other guys knows you know something and may take extra precaution on come in less haphazardly.
Though I understand what you're saying with reach--it is possible for someone to have greater reach, but when you know he's close enough you react. You don't sit there waiting till he's close enough for you to hit him persay. When there's a threat, you move. That could be stepping back or moving in such a way that he's no longer in your threat envelope, it could be stepping one foot back with the same "hey lets calm down" hand positioning (in prep for something more to occur), it could be you punching him before he punches you. No one is saying that you are to stay in one spot and not move at all.
The point was that you shouldn't worry about a threat until its a threat. The shoulda'-woulda-coulda' hypothetical is an endless one and irrelevent to the point being made.
"I don't know if anyone is known with the art of "sitting on your couch" here, but in my eyes it is also to be a martial art.
It is the art of avoiding dangerous situations. It helps you to avoid a dangerous situation by not actually being there. So lets say there is a dangerous situation going on somewhere other than your couch. You are safely seated on your couch so you have in a nutshell "difused" the situation."
