I beg your pardon?
Consider just about any physical belonging — say, a book. When I buy a book, it belongs to me. When I read a book in my home, I expect it to be a private experience (nobody data-mining my eyeball movements, for example).
This applies to all sorts of things. Even electronic things — if I put some files on a USB stick I expect them to be "mine" and used as I please, not uploaded to the cloud behind my back, or similar.
And if we're just limiting ourselves to what we do in public (eg: collecting pokemon or whatever), it's still normal, I think, to interact relatively anonymously with the world. You don't expect people to remember you after meeting them once, for example.
In summary, I'd say that "things in our society" very much include people (and their tendency to forget or not care about you), and physical non-smart objects. Smart phones and devices that do track your every move and do remember everything are the exception, not the rule.
