There are really many examples of network configurations in which you actually want to perform congestion control, even if the peer is "one IP hop away": radio links that are shared through CDMA, switched LANs in which congestion may happen in layer 2, VPN connections that are tunneled through an undeterminate number of routers. 

Or it could be as simple as the receiving node 
not being able to receive as fast as the sending
node can send...
