Enough people from other tables will be lucky enough to make it impossible for you to have 90% of the chips by the time you get to the end. And once you get to the end the M's would be low enough not to give you enough room to outplay anyone to the river. You would have to be moving in a lot pre-flop which will turn the game into a crapshoot. If you have a AKs and an opponent moves in with 65s, you would just have to take a gamble as a 1.7 to 1 fave which is still a crapshoot. The OP is right, you are all wrong. Your chances of winning will only probably improve 5 times if you can see the hole cards of all of your opponent.

Hopefully, the world's greatest poker player (who is a North American from farther north) will have his book out soon so you won't be so that you won't be so misinformed anymore.
