Telling people doing things like SCADA, who absolutely don't want their hot forging press to be globally addressable, that they're "doing it wrong!" is not helpful. This attitude is why nothing short of coercion and blackmail is required to get a large chunk of users to switch.

Literally no one is suggesting this. Having globally unique IPs doesn’t even slightly infer that they should be globally reachable. IPv6 still uses firewalls. It does mean that making an internal resource reachable when appropriate for that specific resource is vastly easier: you open the right firewall port and it’s done.
