Stealing the blinds is not the point here, it's just a fringe benefit.

Besides, if you're playing .01/.02 then that .03 is worth taking if they're giving it up. Think of your game as a system. When you steal the blinds here you're stealing them a lot of times over the course of a session/day/week/etc. You're losing lot of value if you wont steal the blinds of players who are giving them up easy.
