Steel frames are not that thick either, but nobody seemed to worry about clamping them. Mind you, if your really concerned, get an old school chromed steel seatpost, and swap posts and clamp that....
Bicycle frames are primarily designed to be used rather than to be fixed. "Beer canning" is a failure mode that probably won't ever be duplicated while riding.
I have a Nivecrom steel tandem frame that I can feel flex if I squeeze a tube in the center with just my fingers. I wouldn't clamp down on it's tubes either.
