Exactly. Thus far, since BGP4 was deployed, the size of the DFZ has
grown one order of magnitude less than the public Internet as a whole.

I'm curious: how do you measure the size of the public Internet as a whole?

That's mainly a result of policy constraints on prefix length and
utilisation. If selfishness had ruled, we'd be vastly worse off by now.

As much as I'd like to attribute a lack of selfishness to Internet service providers and their customers, I suspect a more accurate answer is that most folks haven't felt a need to multi-home (or couldn't justify the cost/complexity). Yet. I have a sneaking suspicion that will change when folks discover that all their communications, business and/or home monitoring, entertainment, etc. services are critically dependent on their Internet service and new products/services are made available that make multi-homing easier/ more cost effective.
