The Internet only works because TCP (and QUIC) congestion control does a reasonable job of matching offered load to available capacity. Without congestion control, the network is apt to get into congestion collapse, where the network is increasingly busy but getting no useful work done. We saw such congestion collapses in the 1980s. Van Jacobson's TCP congestion control algorithm was the response and its descendents have kept the Internet working ever since.
