One hopes that the costs of consuming routing table slots creates backpressure to discourage needless use, and that the royalities receive offset the costs of carrying any additional routing table slots.
Note that our present system lacks both consistent backpressure on consumption of routing table slots and compensation for carrying additional routes.
The costs of carrying routes is unevenly distributed. when I have to carry 2 million routes in my fib on few hundred 120Gb/s line cards it's a bit different than someone with a software router who just has to make sure they have 4GB of ram... That has very attractive properties along some dimensions. e.g. the cost at the margin of connecting a new participant to the internet is rather low.
