Sure. In retrospect giving the ICC power to set rates looks like a bad idea. Certainly, hobbling the railroads in that way after other, less regulated forms of transportation came along had a very bad effect. But if Roosevelt used the same tactics to promote a better cause, what then?
Roosevelt was on the big government side of the aisle - as such, schemes are necessary to try to get around the constitution aka "the obstacle".
If Roosevelt were "promoting" a better cause, presumably a constitutional cause, then no tactics would be necessary because he wouldn't be employing his lambskin shredder.
By definition constitutional activity is not a tactic.
