If you are a webhoster or enterprise and your business model can not support
multiple Internet pipes, than you have a suboptimal business model (to put
it lightly)
so, CIDR was a bad idea, and we should push forward with one AS per end-site
and a global routing table of 500 million entries?


I think that's unnecessarily one dimensional. The needs of business to be connected in a reliable fashion are above and beyond being for or against CIDR. Rather, they are the requirements for the routing architecture that the Internet has yet to fulfill.

Single homing is bad simply from a reliability standpoint, and the only true technological impediment to everyone multi-homing is cost and the routing architecture. Consider the ability of the average consumer to make use of WiFi to provide mutual backup connectivity to his neighbors with alternate last mile providers. As the cost goes to zero, everyone will want to multi-home.
