I believe that we'll see extensive use of NAT for client-only
services (just look at many broadband residential services
today), but that won't help business customers who want
a block for the DMZ servers.  They'll pay, but the question
is whether they can afford the actual global cost of routing
table entry, or whether it will even be accountable.  ISP's
can figure out the cost of "obtaining" IPv4 blocks, but the
imputed cost of injecting these random blocks into the DFZ
routing table is harder to measure and inflicted on everyone
else.
