In about two years time, IPv4 addresses will be worth on the order of 
$100/IP, assuming current trends hold.

That's a lot of revenue in leasing IPv4 to the business customers that 
refuse to think about IPv6 because $reason.

It's also a lot of unit cost to add to a consumer-grade service, where 
your margins are distastefully thin already (well, in some markets) and 
set to get thinner when you need to buy a swathe of CGNAT boxes to keep 
routing IPv4.

Even at todays's dollar price, this dilemma holds true, but I largely 
suspect that there are too few fixed-line ISPs that have been forced 
into CGNAT yet - the more that are, the more will wonder why they're 
buying so many of them.
