Say ~100k bitcoin held by working class, spending 50% per year, so 50k moving. ~8m are >1k, so 1% per year spending + spent investment is 80k coins moving. ~10m held by 1-1000ers, 2%/yr is 200k coins per year. ~330k bitcoin GDP/yr. With $100T GDP/yr that gets you $300m per bitcoin.
Investment and spending would need to be 10x higher (3m btc/yr) to get down to $30m. Do you really think someone with 10k bitcoin will be spending 1k bitcoin per year?
Why can you not take the everything divided by 21m? -- because you could actually buy everything for a lot less than 21m. You would buy everything for 5m and find you sell at 3m. Rekt. Economic FLUX is the only sensible framework and non-linearity of exit liquidity makes thinking of totals nonsensical.
