Could not disagree more. Everything that affects your use of a language is that language - the standard library, the ecosystem, the community, the documentation, the tooling, every single thing.
The standard library is special. It sets the blessed way to do X, e.g. Context, the Writer and Reader interfaces, etc. Claiming that you may as well write your own is like claiming you can just fork Linux if you disagree with its direction. Good luck with that.
Bringing up Python is particularly unfortunate since its packaging story sucks, so whether a package is included in its stdlib or not really matters.
Sure, argv parsing is an isolated piece of functionality, so in that specific case it doesn't really matter what package you use, but the sentiment is incredibly wrong in general.
