Nothing is perfect in the Universe as you know, in reality. We can't have perpetuum mobile due to friction. But we still can have systems that operate with 99.99% efficiency.

Idk about that. Bitcoin in an unbroken state looks like perpetual motion to me. The universe looks like perpetual motion to me. The blocks never stop. I don’t think we can have a grounded argument in how we value our nodes if we arbitrarily discount some bits over others and allow the chain to grow faster than consensus 1MB. SegWit arbitrarily values some bits differently than others and distorts the entire economical relationship between sats:bits:joules. You can’t support BIP 110 because “Landauer Attack” and turn a blind eye on SegWit, that’s a double spend. In terms of the relationship of energy bits and sats, the root source of sin is SegWit. This is objective. We don’t have a proper fee market to curtail bad behavior to begin with because of SegWit, we need to proceed 3-4x the number of blocks to stop the behavior, meaning we need to appended 3-4x the number of bits to the chain per block to stop the behavior, all because of SegWit. Address the root not the symptoms.
