But it is not.

It is more expensive to carry a large packet a long way than to carry a small packet a long way. Because of things like hot-potato routing, that frequently means the sender has less cost than the receiver, depending on where they meet.

The rest of your argument is based on the premise that none of this is changeable. Which is clearly wrong.

"Receivers" have been de-peering "Senders" for over half a decade. (I.e. "Forever" in Internet time.) These fights have been fixed by things like sending MEDs or intentionally recruiting customers to balance traffic for a long, long time.

Of course, there is nothing wrong with an eyeball network saying "I'll carry it, gimme gimme!" But that doesn't mean they have to.
