The world at large doesn't care what I love, correct. But my users care about whether they have to remember that they're supposed to use port bla instead of the standard port foo, which is a common scenario with v4. Not enough addresses, and / or you can't get them to the VM or container or VPN client or whatever that needs them. IPv6 can often fix these kinds of issues.

Does the world at large care? No.

Do I care? Yes.

Do my users care? Yes, albeit indirectly.

Does my organization care? Yes, in the sense that it removes friction from what it needs the employees to do.

And that's all the justification that's needed, I'd say. The world very clearly doesn't need to revolve around what I love for IPv6 to be a good thing.
