I think there is more benefits that re-raising brings. It gives you a more aggressive table-image and discourages people from bluffing at you. Also if you suspect that someone bluffs at you on the flop and re-raise, they will find it suspicious (if you always call with hands like you described), they will know that 1. that you think they are bluffing, and 2. you probably don't have much of an hand. Do you see this as a problem?
