i imagine most market holdings follow power laws. or is the stock market different in this way because of more widespread pensions/retirement accounts?
either way, a $2T crypto market (i don't know where GP got $3T from: CoinMarketCap.com lists 2.2T) is substantially smaller than a $50T stock market. Governments can and have just straight up injected that demand equivalent in value to that $2T figure into markets in the past, so if we have a crash localized to crypto, it's not as though govts have no recourse.
