By that token, IPv6 never had to exist at all then, but we know that is completely missing the point.

IPv6 is a privacy nightmare without privacy extensions. It is designed with "a stupid desire to pretend we can boil the ocean".

Close to 3 decades and we are barely scraping 50%: https://stats.labs.apnic.net/ipv6/

Running a IPv6-only network that doesn’t interact with IPv4 networks in any way is great and it works.

The actual gap is the mess of mixing/transitioning, and it wasnt planned properly in the last 30years

		Yeah, that is the whole point. It was never going to be a clean cut. "Works in my lab" isn't good enough for real world. The issue isn't that it wasn't planned properly, the issue is that the real world wasn't taken into consideration by people who either worked for the likes of Google who were aching for a globally unique identifier per device or just delusional about how much we can change in real world.
