Speaking of FUD... NAT does nothing here that is not also accomplished
through the use of PI addressing

If you completely ignore the cost of routing table growth to give every company their own PI, sure.

  #2  NAT advantage: it protects consumers from add-on
  fees for addresses space.

More FUD.  The correct solution to this problem is to make it possible
for end users to get reasonable addresses directly from RIRs for
reasonable fees.

Reasonable is a hard word. We've had to turn away customers who wanted to assign a /27 to each and every machine, without actual justification for more than 3 IPs per machine. Sometimes people want to do insane things that aren't technically reasonable, but it's what they want to do. NAT gives them that option.
