Your goal isn't to get your hands to "hold", it's to maximize the size of the pots you are likely to win and minimize those you are likely to lose. If a player to your left has been raising every pot, then limping with the intent of three betting might be a better approach. That's a contrived example but there are other situations where limping with AA allows you a better chance of getting all of your chips in (with AA) pre-flop.
Sure, 99 times out of 100 raising AA from early position (or any position) is the way to go. But, you can't think in absolutes for two reasons: 1) You'll miss out on some rare but profitable opportunities 2) Your more observant opponents will know what you're doing and pick you apart.
Just yesterday, a guy to my left was raising my limps from early position (really he was raising every un-raised pot). I pick up KK and limp, he raises, I 3bet, he folds. I pick up AA on the next hand. I limp, he raises, I 3bet, he shoves.
Sure, I got lucky. But a little luck and some non-standard play allowed me to stack this guy where standard 3xBB raises probably would've just gotten me the blinds or a small pot.
