Thank you for the thoughtful presentation and conversation. I am cautions by nature and this feels abstract. If you have a moment, could you briefly explain what is definitely lost if the block size stays the same?

Main point is on the goldilocks slide. Demand fluctuates due to a wide variety of factors. If supply is static then the likelihood that the supply is optimal at any given point becomes quite low. If cost of block space is too low, it has centralizing effects / makes thermodynamic security unsustainable. If cost of block space is too high, it also has centralizing effects / pushes users to trusted third parties or other networks.
