Or something.

Possibly.

You have successfully demonstrated that users will need some locating
service. More so with the cure-all IPv6; because remembering hex is hard
for People(tm).

You have, however, not shown that all the possible ways of building a
locating service that become available once the end-points are uniquely
reachable (and thus, as long as we're OK with finding just the right host,
identifyable) present an equal level of suckage.

I believe that while the work indeed can be daunting for a sufficiently
pessimal selection of users, the situation so improves (if we look at
simplicity of protocol design and resulting fragility) when the end-points
can ignore any middleboxes that the net result, measured as inconvenicence
imposed on a standard End User, will improve.
