TFA is suggesting almost the exact opposite. "Servers" are moving more and more to an architecture where the service is a distributed collection of machines all over the world sharing only a DNS name; multiple servers share the same physical box, relying on TLS SNI to decide which particular content is intended. While NAT itself would be a problem, the reality is that a service no longer needs some unique IP: the same public IP can be shared by Netflix and Max, and the only relevant thing is that the incoming connection specifies which of the two is intended through the DNS name.
SNI took the pressure a notch down. It was introduced 2012 and graph in article was showing peak of price of IP address in 2021 - where everyone was watching Netflix all day or was in video calls. SNI is not solving video streaming problem you just need more physical networking gear to handle streaming and more public IP addresses.
