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.
