So, assuming:
      1.      There are actually 8 million point to point links in the internet
      2.      All of them are currently /30s
      3.      Absolutely optimum use of addresses for all those links
      4.      All of them are converted to /31s

(none of these assumptions is likely in fact)

In particular, if your site has 256 PTP links, you can convert from /30s to /
31s, save 128 IPs, but then trying to *actually use them* effectively outside
your AS ends up sounding like this:

"Eat your Brussel sprouts. Don't you know there's kids starving in Africa"
"OK, you can send my sprouts to them..."
