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.
Regulations and quality checks on aerospace parts is no joke. More so on stuff that goes out into space and on military hardware, but every single nut and bolt and everything in between can be traced back to a supplier and that supplier will be able to tell you when it was made, by who and even where the raw material came from and show you the certs. Regular airplanes not nearly as strict or as much paperwork, but it isn't that far behind, quite honestly.
Also, you might be surprised by the testing that ladders go through. Not so much the cheapo Chinesium stuff, but safety in all fields is no joke. It is too costly to skimp on testing.
I used to believe this, but recent incidents have exposed systemic issues in engineering and QA at at least one major US aerospace manufacturer.
