If your argument can only be made in a very specific set of conditions and only applies to yourself, it's just a preference.
I don't care how you prefer to do things on your own, but if I were interviewing you for a senior position in a team with a handful of people, and you tell me that's how you want them to work, it would be an almost immediate NO HIRE.
Yes, but you are moving goalposts. I was under the impression we were talking about the one-man army case only, not how they conduct themselves on interviews which is a VERY different topic.
The blog post was about the context of a team with multiple people.
OP's comment was "I do this for my Go project's" and goes on to describe how to use a (open source) library that even deploys to Hetzner.
So, either the commenter was trying to extend their practice to the point of the blog post or the comment was just expressing a preference when working by themselves, which has little to do with the content of the post.
Sure, I don't think we disagree as much as I thought an hour or two ago, I am still little puzzled why you found it so bad though.
If a deployment procedure is easy for non-DevOps people then by definition that also makes it friendly to programmers, so why wouldn't they do it if it they can do it properly with minimal effort. But I do realize that "properly" is doing a lot of work in this sentence.
