Unfortunately, individual actions would never be enough to solve the IPv6 chicken and egg problem. See djb's "IPv6 mess" article:

Yes, it is old, many examples are outdated, but the main points still hold. Decades later his suggestions for making IPv6 succeed are still not implemented.
It's not a lot but it's better to be part of the solution than the problem even if it is an insignificant contribution.
This stuff is obvious now, but I think back then this was probably quite clever.
