Good luck prosecuting them for that.

Along with all the internal IT departments that are failing to deliver v6 to wifi and desktops.

Right. Now it is only people who can afford about $8 one time. (The going rate for IPv4 on the transfer market at 
modest block sizes)

Most consumer ISPs also prevent this as a matter of policy. Good luck getting those policies changed.

if the goal is to serve "most of the users on the Internet"

Last I checked, things are still working out just fine for all of them. Despite the obvious concerns about the future.
