Luu could achieve his goals while still adding basic things like padding, margins and better structuring of his paragraphs.

Absolutism on either side of this debate is purely ideological and does little to serve the user the best possible experience.

I am user who thinks I’m getting a better experience, so I think his main point is right - you are expressing your preference with the voice of the general user, and moderation.

"Better" is subjective and debating such a vague generality will get us nowhere.

Instead, I will focus on more objectively measurable aspects such as flexibility and ergonomics. You may be getting the most flexible reading experience, but you are getting the most ergonomic reading experience. You also have to put in up-front work to get a better experience, or rely on tools like Reader mode.

If that's what you prefer, that's fine. If you weren't aware, in most browsers you can access the menu bar and navigate to "View -> Page Style", and set it to "No Style".

Then you're free to add whatever styles you'd like on top. Meanwhile, the casual, less technical, non-designer user can still engage with the content in an accessible and easily parseable manner.
