Pragmatically, you can design things to be highly readable for yourself and people that are "like you".
Alignment between the shape and the content is done in a circular fashion : what you see educates you to fabulate about design, once you fabulated enough you begin to say things are bad or well designed.
I often express myself online by writing a bit what goes through my mind, in a joyful and not very attentive manner, and I find it amusing to be barely understandable sometimes (I like the fact you had to use an LLM, lol) because, well, I feel it may bring a certain color to the otherwise often too uniform and immediate/instantaneous world of internet -- So, what I said previously is also mostly what occurs when you let your mind wander;
now, if I rejoin my own person and body, I can agree with you that my culture of good design is about the testimony of the removal of intention, in such a way that I feel content is highly readable, (fictionnaly) devoid of style, and somewhat raw or pure.
But again, at the "philosophical stage" all of this is pure fiction, and with a certain mindset, I am pretty sure I could shift my habits to adapt to what I feel as weird design, ugly, barely readable etc... It would be totally useless and absurd, but I could (given I have no specific perception-related medical conditions) !
We saw the web become a repetition of the same design, and while it IS good design in our "minimalism" addicted brains, I am pretty sure stumbling upon weiiiiird websites makes us great good sometimes, so much that maybe we also start to think about the absurdity of our standards : we arrived to the point in the "lie" where we identify this specific style as "the shape" of our perception, and yes : it become invisible to us, and is good design, but also it is a bit depressing.
My window manager and my emacs/vim/terminal configuration aren't what I call good design. They are highly readable but stratosphere-reaching levels of kitsch (yes ! I WANT to cosplay and feel as if I was writing code for aliens or to fight the matrix at work, and yes that's a bit cringe but at least I am honest with myself).
I don't wish the world and internet to be "more like that" and am ok with the actual state of design. Nevertheless I find that's a bit arbitrary and somewhat boring.
