I'll take a shot at this...

#1 Because the real junk hands can put you to a difficult decision. You might flop a pair with a crap kicker and your opponent shares you hand. If you call with low crap cards the board will pretty much come with overcards. You flop a 2 with your 23o, how confident do you feel about that pair? About your kicker?

#2 Also you don't make as many hands on the flop with junk. What makes more hands 76s or J6o. J6o is technically better HU. The 76s gives you a greater chance to hit some piece of the flop.

But I can see your point. If I knew what the other guy had I would call with any 2 cards considering his raise was reasonable and I knew he DIDNT have a medium to high pair hand. 2/3 of the time he is missing.
