It feels like the same people who make this argument are also using the other side of their mouth to lament that nobody uses containers for their original purpose of containerization. And yet, that's a legitimate use case that is totally orthogonal to any build process or artifact distribution method. In fact the argument itself betrays a misunderstanding, because the underlying complaint is about using Docker images as a build artifact, but it's presented as if containers are the problem. But they're separate concepts (you don't compile a container, so the snarky analogy to static compilation is nonsensical upon closer inspection).

There are plenty of good reasons to containerize even a single binary executable, as demonstrated by the fact that officially maintained images exist for containerizing processes like Postgres or haproxy. Sure, you could run both Postgres and haproxy as services directly on the host, but then you'd miss out on all the benefits either provided by or complementary to containerization, like isolated cgroups and network namespaces that make declarative service orchestration easily achievable with maintainable configuration.
