Your criticisms are mostly correct. I wrote the post to justify my actions rather than tell robust truth. Posting it as-is on LessWrong was my mistake.
“Entangled closer with physical reality” was a poor choice of words. I meant something closer to “experience my surroundings in more detail”.
Reducing what you need implies broadening what you tolerate, in the same sense that a system with fewer axioms has more models. Interpreting it as twisted greed-avoidance is novel and odd to me. If you get used to walking barefoot, then you can better handle situations where you lack shoes. On further reflection, that broadening is small compared to other methods (as learning a language).
