Personally, I like to occasionally remember that there's not a single computing device in my life I really own. It can be either a comforting piece of knowledge or a frightening one depending on your perspective. I like to take the former perspective.
I see what you mean, but also no one ever owned a loaf of bread that could be cut, toasted and buttered remotely by a totally unknown 3rd party either...
Good point. You walk into the diner implicitly trusting the line cook and the bread baker and so on. Very similar to the chain of trust implicit in the tech we use. Only I believe the chain of trust in the tech to be much longer and proven to have been repeatedly broken in recent decades. Also, line cooks have the luxury of tossing out loafs of bread that have moulded over.
