Thanks, Jack! I have a few follow-up questions, if I may:

"Physical world (universe) must be closed mathematically (hence Planck Temp = 21M cap in equivalence). Without a boundary there can be no meaning, measurement or time."

The physical world is energetically closed (21Mx10M sats, ignoring issuance) but, just as Bitcoin is not a closed system in other ways, notably signature inputs, do you think the physical ledger can have other kinds of input?

"The universe is its own entire ledger, bitcoin is a bounded fraction, or partition, of said ledger. It’s a fractal of the same thing. It’s all just peer to peer “cash” (energy) systems. There are only p2p transactions."

Can you tell me what it is to indicate that it's fractal in this way? I see Satoshi as having done something quite unique, in physically implementing an analog of conservation, aka "the invention of digital scarcity". This seems quite different to me than saying that, this recursion not withstanding, the world is a fractal. I wonder if this is a point I am missing. What shows us that it is a fractal? Is this about how information is integrated at different scales?

Also, just to be sure, what are peers? Are those addresses in the keyspace?

"Ledger > Money"

Can you say more about this? Do you mean this to describe causation?

"The rules of the universal ledger must be extratemporal to the ledger, meaning they must exist outside and prior to the time it produces. The ledger upholds the rules it was given. Only from the structure of bitcoin can we deduce what must be prior."

I'm a little confused by this. In Bitcoin terms, the rule exists and the rule is not the ledger. The ledger is a product of the protocol. But I don't think the ledger upholds the rule. Maybe you meant that the other way around?

I agree we can only infer prior states may have been from current state from within time, based on our imperfect knowledge of the rule. Do you think the rule is deterministic?

Thanks again!
