>9/10 times, my net displacement for the day is 0. If my net displacement is zero, I would prefer to own the medium I'm using to move.

I don't. 9/10 times, despite zero net displacement my commutes are asymmetrical — on my way there I'm in a rush, but on the way back I'm not. So I'll often take a high cost, high speed option like a scooter towards a destination, then take a more leisurely, generally free option like walking or transit back home. As a bonus, I never have to deal with storing my vehicle while I'm at my destination, or with taking it with me if I add an intermediate stop nearby before returning home.
