If he can float me then min-raise knowing he'll get two cards when I have a hand, a fold when I don't and license to value bet my stack when he catches really good then he has established a wildly profitable dynamic which will encourge him to play pots against me with position and play them well.

As much as we may LOL at his SB complete with KK, if he can exploit weaker players like that he can make up a lot of ground from his poor and obvious pre-flop errors.
