If you never lose stuff of value and importance, why do you want to tag stuff of value and importance? If you’re getting those things stolen it sounds like you do have a problem taking care of them if they’re not getting stolen, it sounds like you don’t really need to tag them. Not trying to argue, just trying to figure out your use case.
I never lose stuff but it doesn’t mean things don’t go missing for me. A good example would be sporting equipment, like badminton rackets, etc. They were in my school gym locker, but broken into. My dad also lost a filmography film DV, the type you use for 35mm movie production. It was in the trunk of the car, but was broken into. The entire equipment set was stolen. The cops couldn’t do anything. If only it was tagged with a few AirTags, it could probably be recovered. Since there are only a few of those around, it’s not difficult to prove that it belongs to you. If you can find it.
