On the other side, local production (National or regional) will be cheaper by comparison. If people purchase based on price it would force fiat to remain within the naional system. I'm not saying thats good or bad just a statement. The opertunity in this problem is to refocus on local production and by extension push bitcoin adoption as the contraction in fiat effects inflation.
If fiat remains within the US rather than being exported then domestic inflation gets worse. You don't boost local production by raising taxes to cut off the supply of cheap tools & capital equipment. I just bought a Chinese excavator for half the price of anything I can get here. I buy most of my tools from Harbor Freight. Making my tools and certain supplies more expensive just increases my cost of doing any sort of business. You want to boost domestic production you remove govt licensing restrictions & cut taxes. You don't increase taxes on the flow of inexpensive stuff.
