You still need enough reserve power at the end of a flight to do a rejected landing/go around, or you won't get certified. If you are relying on some kind of catapult, rail gun, or rocket assist to take off, not sure how that happens.

An early rejected landing still requires less power than a static takeoff, so you could get by with a mix of craft and assistive power.
