On one hand, the amount of content that is 'live' or 'continuous' and 
suitable for multicast streaming isn't s large percentage of overall 
internet traffic to begin with.  So the effect of moving most live content 
to multicast on the Internet would have little overall effect.

However, for some live content where the audience is either very large or 
concentrated on various networks, moving to multicast certainly has 
significant advantages in reducing traffic on the networks closest to the 
source or where the viewer concentration is high (particularly where the 
viewer numbers infrequently spikes significantly higher than the average).

But network providers make their money in part by selling bandwidth.  The 
folks who would need to push for multicast are the live/perishable content 
providers as they're the ones who'd benefit the most.  But if bandwidth is 
cheap they're not really gonna care.

It's an argument for decreasing traffic and improving network efficiency 
and scalability to handle 'flash crowd events'.  IPv6 has nothing to do 
with it.
