But even if all these assets add up to, say, 1-2-3 quadrillion, you can't have another 1-2-3-5 on top of that because it's a zero-sum game where something must be spent to buy the crypto so that its price goes up.

(What's spendable is typically the money - in other words, best case scenario is the total replacement of money with crypto, so, say around 100 trillion).

But I think crypto will be in the triple-digit billion or low/single digit trillion range. Which is 100-1000x compared to current valuation...
