The combination of "people will be using multiple ISPs simultaneously"
and "large networks will be hellishly inefficient wrt /48 usage due
to internal aggregation" (which RIR policies permit) this is not plenty
as it looks like. A waste factor of 1000 in a network with many layers
of aggregation (BRAS, POP, City, Region, Country) might seem gross, but
we'll see that. Look at the HD ratio tables...

Works for me :)
