It can't because of mana efficiency and instants. I can cast my stuff at the end of your go, tap you out, untap, draw, and have a second go at you while you are still tapped.
Thing is, counterspells are good if the other guy can't kill you by round 3 or so. But Red burn would have done a massive amount of direct damage to you by then. It only needs a bit more to kill you outright. With untap-burn, don't forget that Red can also counter your Counterspells, and it only cost them a Red mana to do so over your 2 Blues. Draw-Go actually puts a Blue player at a disadvantage vs fast Burn Red as it fills the Red player's hand with instant, high efficiency burns that a Blue player would have a hard time countering all the time. That is, unless you somehow survive until the late game, when you have Islands to Africa. Then Blue just wins.
Blue Control would be very nasty vs Weenie decks. Of that I have no doubt. But it is not 100% effective against them, either. If your anti-creature defenses doesn't come out fast enough and in sufficient quantities, you will just be swarmed under by a lot of little guys. Trust me, I have played against a lot of Blue players (just practically everyone but me in my group of about 10 guys played Blue of one stripe or another). Counterpost, Draw-Go, Blue-Black Mill, Palinchron, Fire and Ice, Counter-Drain, you name it, I have run against it.
None of the decks are 100%, of course. No decks are as luck still has a big say in things. But Red burn and Sligh does have the best chance against all decks (like in tournament play). Their main weakness is against Life Drain decks, but even then, it is a case of quickdraw.
