This comes up now and then.
I was taught by my parents and every mentor my whole life to appreciate and respect all things and my father was a master machinist. Taking care of tools is a way of life for me. So, yes, if there are protective cases, bags, bottom plate protectors, etc of course I use them. 🙂 in no way have I ever used anything that hindered my usage of gear. In fact, not protecting my gear would eventually be a huge hindrance.
Aesthetically, I also appreciate well cares for instruments whether it be a Leica, Nikon or whatever. I have restored many cameras and they look like new.
I do the same with cars, furniture, home, and everything. There is a whole mindset that goes with that. Either one understands that mindset or not. Everyone is different.
I happen to live life that way... That's just me.😉
