If you tell me that every enterprise on the planet can easily get a /48 routed at no cost, then indeed that's probably the right way to go.   I will defer to others with more experience in these matters to tell me whether or not that is so; my understanding hitherto has been that it is not.

Let's assume a paltry 5 billion homenets, each with a routed /48.

Well, today BGP-4 has 17687 entries for IPv6, according to
http://bgp.potaroo.net/v6/as2.0/index.html
It will be interesting when that number changes to 5000000000.

Somehow I doubt this will happen. Quite how far we go in that
direction is an interesting question.
