It goes both ways. If you increase your bet size too much on bluffs, it becomes profitable to just wait for a good hand to call you with and fold everything marginal. The bigger your bluffs, the fewer I need to catch. You'll also become predictable if you only overbet when bluffing. If you try to deal with that by making all your bets larger, then you lose out on value from your strong hands because I can now profitably fold some hands that I would have had to call you down with otherwise. Put another way: you can't exploit someone who makes decisions based on pot odds just by changing your bet size, because changing your bet size changes the pot odds.
