Stackoverflow's quote you pasted makes me feel like an old fart on the Internet. I imagine there are a lot of rose-tinted glasses at play here, but I kind of remember an Internet when we would do things for the good of the network as well as for the good of the user.

Taking action as a group to speed adoption of a technology that makes the kind of innovation and autonomy we had in the first thirty years of the Internet accessible to the next thirty years of the Internet is impactful for users. The gigantic companies who have bought /8s and /9s of IPv4 space are not going to undermine their investments. It will take companies and network operators who are big enough to decide but small enough to still be idealistic who say "yes, IPv6 is worth it and we are going to spend the time and people and money and resources on doing it."

This is the same problem we have with housing; it can't be an investment and a thing everyone needs. At least the difference here is probably no one winds up hungry under a bridge taking ill-advised substances to handle daily life simply because they don't have a /24 to call their own.
