You seem to always advocate that any given idea must be instantiated and explained by some specific physical circumstance. That is so alien to my way of thinking that I actually find it interesting. But you could consider what I say interesting to you. I say that we can consider a process whereby a structure (and we as observers have to decide how that structure is to be detected or observed) is maintained even though the component parts of the structure are seen to change over time. Indeed we are thinking of the structure itself as showing how it uses material from its environment to form itself and so continue its form. Such a process is called autopoeitic. But there are many examples of such structures, with different kinds of physical substrates. The place where your way of thinking comes in is when I have a more grandiose thought that perhaps what we call the Universe is autopoeitic. But then the Universe should be its own environment! I do not believe in closed system autopoeisis. So I correspondingly find that I do not believe in a closed universe.</div><div class="">If you ever imagine that you have defined the Universe (Wolfram once said he thought he could do it in a thousand lines of code) you will find that it has escaped your definition.

In the case of homeostasis, the exaptation refers to the chemical 'balancing' of hydrogen and helium reacting iteratively to form the stars (Stellar Nucleosynthesis, Hoyle, 1946), the byproducts of which were the elements in their exact order of their atomic masses from 1 to 94 as the 'logic' of the Cosmos. Fast forward 10 billion years, and life is evolving due to symbiogenic (Sagan, 1967) assimilation of the elements in order to maintain their homeostatic balance in an ever-changing environment, assimilating the logic of the Cosmos......and this is the foundation for both local and non-local consciousness.

Who can deny that? MUV point out that a living organism consists in an organization that keeps replenishing its materiality while at the same time maintaining its organization. They further raise the question about how such organization can arise in the first place, giving a very elementary example of such an emergence. In this way they provide a framework for thinking about organization and process that is more general than biology and that lets one think about these matters without dogma. In order to do so, one must avoid making dogma out of MUV and now we arrive at the problem. The problem, as I see it, is in academic discussion -- which normally depends on making references to previously published work, each such work being regarded as some kind of steppingstone to the building of an imagined edifice of thought. But you just cannot maintain that sort of structure unless you have the kind of foundational criticism as occurs in some parts of science such as in physics an mathematics but is unfortunately not present elsewhere. One can eventually discard the shells of useless thought (like phlogiston). MUV is not providing us with a possible phlogiston. They are providing us with general principles of organization for structures that persist in time.

About the obvious need of, say, an energy flow there is no realization that a previous sensing of ALL those items is needed. The revolution in prokaryotic signaling brought by the discovery of "One Component Systems" (in the hundreds in each bacteria) in last two decades clarify that point--how the external substances are first "tasted" and later introjected.
