What you are saying is the cost to operate the network increases, sometimes to the point where the privacy makes the network unusable. This is the operational experience. 

It also means things like my ssh sessions can't last long enough to do large transfers as the address is rotated away. 

There is more to the internet than browser activity. The noise of NDP for all these addresses has a real cost. Some of the problems are documented in 6583. 

A network that doesn't work is not the goal but it will have the privacy you seem to be reaching for.
