Except it stands to reason that the longer the crank, the harder it is to spin, even if you change the gearing to compensate, right?
But you don't have to spin, because you're pushing a bigger gear. Within the ordinary range of crank lengths, your speed for a given effort is the same if the gain ratio is held constant.

And there must be a flipside to this, otherwise the ultimate crank length would be 1mm.
