The short answer to "why do people connected already cannot just stay connected" is "because the IPv6 network is a different network".
Of course, this is not the question you meant. What you mean to ask is, if I am understanding the massive sprawling thread forest (but please correct me if I am wrong), is something like "why could not a transition plan be made which would allow for the IPv4->IPv6 transition with no loss of connectivity at any moment". With an implied "if everyone followed DJB's plan, it would have worked".
Leaving aside DJB for a moment, this is NOT a simple question. It is also VERY technical. Either you use a heavy amount of jargon, which can be impenetrable to anyone who does not have a deep knowledge of the Internet architecture, or you use a simpler (but still very technical) language and your answer becomes quite long. To make things worse, most of it would be showing hypotheses of possible plans or parts of plans and explaining where they fail.
As to DBJ's plan, here is why it would not work: "Once these software upgrades have been done on practically every Internet computer, we'll have reached the magic moment: people can start relying on public IPv6 addresses as replacements for public IPv4 addresses."
With DJB's plan, we could only START using IPv6 addresses after PRATICALLY EVERY INTERNET COMPUTER had been upgraded to understand IPv6!

Aha. The real problem right there.
> With DJB's plan, we could only START using IPv6 addresses after PRATICALLY EVERY INTERNET COMPUTER had been upgraded to understand IPv6!
As compared to now, when we cannot start using IPv6 addresses at all as well. Because not all of our computers understand IPv6 (tiny minority, not the real problem, easy to fix) _and_ they are not configured for IPv6 as well (vast majority, the real problem, will take lots of effort to fix).
Now, if we were able to deliver parallel, but not configured IPv6 stack to almost everyone, surely we could have delivered integrated, fully configured IPv6 to almost everyone already connected with IPv4.

Completely agree. A good example is the current IPv6 transition plan.
> "Your idea will not work. Here is why it won't work. [...] ( ) Requires immediate total cooperation from everybody at once"
Also agree. Essentially, everyone has to cooperate by reconfiguring their networks with brand new IPv6 addresses, DNS, firewalls, daemon configurations etc. End result? 0.3% penetration months away from IPv4 address exhaustion.
