Your footnotes basically invalidate your argument. You aren't just deploying a tarball, you also have to deploy the java runtime and make sure it's compatible with your application.

I agree that Go fans make too much of the single binary feature, but it does seem easier than your deployment process.

Of course your process is easy for you because you built it to fit your needs. But if you imagine a new developer who has no experience deploying either Java or Go applications, and consider what's easier to deploy without any previous knowledge or automation, I think you might agree the Go deployment options are simpler.
