This doesn't make any sense. The point is not to get rid of them. The point is to have them pay you while you are ahead. Additionally, they know they need to hit a big hand to win, however, you will have a hard time folding aces. Limiting the number of players in the pot will reduce the likelyhood that they hit a big hand. On top of all that, putting more money in the pot before the flop will make up for the times that your opponent makes a big hand and stacks you.
If you think the purpose of raising is to make weak hands fold, you obviously don't know how we make money in poker.
