Trying to summarize my current understanding of what you’re saying:
Yes all four sound right to me. To avoid any confusion, I’d just add an emphasis that the descriptions are mathematical, as opposed semantic.
I’d guess you have intuitions that the “short description length” framing is philosophically the right one, and I probably don’t quite share those and feel more confused how to best think about “short descriptions” if we don’t just allow arbitrary Turing machines (basically because deciding what allowable “parts” or mathematical objects are seems to be doing a lot of work). Not sure how feasible converging on this is in this format (though I’m happy to keep trying a bit more in case you’re excited to explain).
I too am keen to converge on a format in terms of Turing machines or Kolmogorov complexity or something else more formal. But I don’t feel very well placed to do that, unfortunately, since thinking in those terms isn’t very natural to me yet.
