I’d say the difference is that every single part of an airline is carefully rated though. Everything that’s supplied for use on an airline is expensive because of all the regulations.
A ladder may be rated for 1200 pounds, but nobody inspects every single use-case for that ladder and ensures that the entire system always has 4x safety. Once you buy the ladder it’s up to you what you lean it up against, etc.
