the security controls for a bike on a high mountain are not obscurity, they're the lack of oxygen (that kills), the cold (that kills), the height (that kills), and the literal sheer difficulty of getting there.

you could put the bike right on the side of the mountain without any obfuscation and it won't get got because ain't no one gonna die for a bike.

its like how we know where dead people are on Everest but we can't get them down; they serve as landmarks.
