My comment was directed at the incorrect statements that sound like facts that the author made.

I am not saying that people are born knowing how to use Hugo. Hugo is powerful. If you want to tweak it (the theme), change how your site looks and all, you would need to understand how Hugo works, learn templating,etc.

If you are happy with one of the existing templates, you don't need most of that.

Nothing comes for free. You either learn or live with what an existing theme has. I think, this applies, to anything in general.
