I can appreciate this perspective but, like others have said, it is probably useful to add a "for me" and "for others" qualifier to these observations and see that there is no universally true statement for all people.
I have considered "meditative" to be a part of my character for nearly my whole life, while it is self-taught/self-discovered and idiosyncratic. I would read some popular accounts of meditation and hear parts which resonated and parts that just didn't seem to translate.
I already am aware of my breathing. I discovered "square breathing" for myself as a child for pain and stress management and got lots of breath-awareness through swimming. I find it odd to imagine being unaware of breathing, but I realize it must be possible from the accounts of others.
I am self-reflective and aware of my thoughts and emotional responses. I had difficult aspects to my childhood and had to learn to modulate my responses and predict the unpredictable to deal with volatile personalities in my surroundings. I find it odd to imagine being unaware of my thoughts or emotions.
In recent years, I've struggled with stress management and found myself stating things very similar to your final line. I hear people telling me to do these beginner-level meditation steps and I simultaneously feel, "I am already doing this," "it is not working," and sometimes "your advice is not actionable!" while feeling very frustrated. I might blurt out any of those statements if I get past feeling it is pointless to continue the interaction. On reflection, I think it may be impossible to know which is more true of the apparent contradictions. Am I not doing it even though I think I am? Is it working even though I don't think so? Is it really meaningless advice or I am just being petulant?
These guides and advice are written for a target audience. They are not really wrong if they do not work for some of us, as we may not be the audience. What is frustrating is that it can feel impossible to find alternative guidance if you have an atypical starting state. What is alternative advice about "being present" for someone who is stuck in hyper-vigilance due to stress/trauma? What is alternative advice about "recognizing your thoughts" for someone who is stuck ruminating and meta-ruminating? Etc.
