Agreed, peering on a single connection is a canard.

However, there is a cause/effect relationship with the latter. They can't multi-home to multiple providers because they aren't big enough (can't justify the cost). Which is precisely part of the problem that I am presenting here.

The reason this is an issue is exactly because they want reliability and availability, HA requirements.

I actually agree with you here as well. relying on infinite router table growth is not a scalable strategy. We need something else.
