That’s not the real goal of cryptocurrencies. It started off that way—remember people buying pizzas and domain names with bitcoin? That is the sort of thing that people do with dollars. But it became quickly apparent that cryptocurrencies suck as currency because they are so strongly deflationary. However, that makes them work great as commodity financial instruments. So viewing crypto as a financial market (not a currency), it benefits the U.S. to have as much of the market transacting within the jurisdiction as possible. Then you get the tax benefits, and ancillary benefits (e.g. rich crypto owners buying things).
