> As a complete lay person with little to no physics knowledge: what stops the use of something dumb like a parachute, or even wings and landing gear, to "land" the booster?
The main advantage is that you don't need to spend any of your payload mass budget on a parachute, or wings and landing gear. The secondary advantage over a parachute is that you don't need to fish it out of seawater and make your refurbishment process more of a pain in the ass.
