I don't think ARIN has the traction to enforce this, and as a member
I'm not keen on ARIN gratuitously blowing its "war chest" on lawsuits
over this sort of thing.

Historically, I've been in favor of making sure everyone has an IPv6
netblock and various outreach programs so that they know what to do
with them.  Beyond that, though...  in the words of Yogi Berra, "if
the fans don't want to come out to the ball park, nobody's gonna stop

As with many other technologies, there is a substantial last-mover
advantage to going dual-stack or single-v6.  Hard to fix that without
resorting to force, and governments do like to reserve that capability
for themselves alone.

No matter how well-intentioned that idea is, actually trying to put it
in motion is a Bad Plan.
