apply this logic to john carpenter movies and they fall apart, too.
Escape from LA is just about as absurd, just less paranormal.
Nuclear powered personal submarines, surfing typhoon waves from California plate shifts, transforming bullet-proof stealth helicopters, emp superweapons and engineered DNA-tailored superbugs ( or atleast the claim of them ) , VR replacing reality, Cuba taking over the democratic world after a theocratic US rescension.
it's just entertainment campiness. When I play a Kojima game I just sort of imagine it internally as a video game equivalent to a John Carpenter movie.
