The physical analogy is different because a hundred years ago we couldn't infer a lot of very sensitive and private information from easily accessible public info. Hell - our longest lived president was wheelchair bound and wouldn't have won his last election or two in the modern day. The only reason he got in was because they hid his disability from the public. Can you imagine trump getting away with that now? Back in the day of physical goods privacy was plentiful. Now it's a scarcity. The difference is not just between physician and intangible property. It's a complex matrix and at some point we have to protect citizens to accomodate to the world that we live in.
