> As I'm typing this I wonder what we would use for shock absorbant things like phone cases or water proof seals like cv boots on car suspensions.

Respectfully, CV boots on car suspensions have a lifespan of several years, same with phone cases potentially.

As a first step I'm more interested in replacing the things that hundreds of millions of people discard multiple times a day. Starting off by thinking about CV boots and phone cases strikes me as being precipitously close to the "we can't replace everything so lets replace nothing" path.

Not at all, I agree packaging and liners should never need to be plastic. Lets ban them now. Glass and ceramics can replace almost everything that metal can't. Recycle the metal and reuse the glass/ceramic. I was just astounded how few things really needed to be plastic.
