I understand what you might mean by "security."

if anyone has keys/access code, etc. to: the guns cabinet, the car,
the bank vault, the missile silo launch console, the candy jar,
and yes, the occasional GA airplane, said person can use that piece
of equipment to whatever legitimate or nefarious end they chose.

That's what keys are for, that's how it works.

How would you suggest preventing it from happening? why should
(and how could) GA airplane be more secure than guns cabinets,
cars, bank vault, missile silo launch consoles, or candy jars?
