The second and third examples are safety lockouts [0] working as intended: Some system is locked in the off state to ensure safe access for technicians.
Especially the padlock lockout is simple and effective: As long as you have the key in your pocket, you can be sure than no one is going to turn on the meat grinder you are cleaning.
The STOP and RESET buttons are from a Documation card reader.[1] They're not guarded. They just come from a standard kit of buttons and lamps where you could assemble the components and dividers into a control panel. That style of illuminated push button was once popular and is still available.[2] NASA Mission Control consoles had lots of them.

The IBM electronic typewriter with the perspex guard is absolutely beautiful.
Yeah, it’s funny how IBM managed to be both absolutely undeniably corporate and somehow still incredibly beautiful. I think it’s just a testament to the visual pleasure created by knowing someone really truly cared about what they were doing.
I would really like to know which museum in Germany this is from.
It's in Dortmund: https://www.dasa-dortmund.de/en/

Just to nitpick, in the section after "On the other side, these following guards are more of a “you really shouldn’t do this” variety – much closer to a disabled state in graphical user interfaces:" The second and third examples are safety lockouts [0] working as intended: Some system is locked in the off state to ensure safe access for technicians.

For the power button is located next to two USB ports I use and, for whatever reason and although it's a very good PC tower, the button is ultra sensitive.
So I created a "not-molly guard" that "plugs" into the two audio jacks (which I never use and which are, also, next to the power button) and that only leaves a narrow hole and a guardrail of a few millimeters.
Printing it in black, matching the tower's lip where the power button is, and life is good. Already hit that Molly guard several times by mistake so I figured out I already saved more time than it took to design it.
As it's a small piece, it printed in a few minutes on the 3D printer.
P.S: AFAICT there's no software setting (?) to prevent the power button from doing what it does!? But who cares, I've got the Molly guard now.
