Replying to Thule one key system and a cross rail mounting ?

With how these locks mount and secure to the bar, does anyone see them as worth it? I’m no thief but I look at it like how someone could steal my stuff, and while the plastics a joke, I don’t see the metal being much better?! I could easily unmount this whole system with 1 tool , metal locks or not 😐 my skis etc will be in lodge or whatever, I’m worried about my rails and cargo box that’s $2g 😡
And my Jeep has the fix point mounting system, the Thule mounting kits screws into the Jeeps rails, anyone using thread lock on these?
