Yep, if ever there was an underground economy, this will ensure it’s advance a billion fold.
There’s always an underground economy. When governments make it too difficult to survive legally, then the illegal/underground market will make up the difference. Years ago, in the late eighties, we had a Polish friend in our home for a month or so. He took care of his family by running a home business collecting yarn refuse from state factories and having women handknit socks which he sold in the underground market. He did whatever it took to care for his family. I still have some of those socks he brought us as a gift.
