As someone who is leading a commercial effort to do just that, I agree
wholeheartedly.  ;)

(Even if we are doing an "air-breathing first stage": an airplane to get
the rocket from airport to a patch of sky far off the coast, where the
rocket is dropped off and ignites, having already been given initial
horizontal velocity as well as skipping the thickest part of the
atmosphere.  Much safer that way, as well as cheaper.)
