I'm building a torsion box with plywood strips for sides and ribs. A
friend suggested I clamp several strips together and run them through
the planer once on each side to guarantee uniform width (being very
careful that the clamps are well below the top surface).

Then I read in Tage Frid Teaches Woodworking not to run plywood edges
across the jointer since the glue would put nicks in the blade. Would
not the same would be true of the planer? IOW, even though my friend's
idea might be good theoretically, it may toast my planer blades.

Can anyone confirm or deny the wisdom of this idea?
