Apologies in advance for how stupid this probably sounds, but just an idle thought:
We all know globalization gives US workers less leverage than ever before, but what if it could be turned around in their favor? What if a bunch of workers in some company in the US decided to form a union and go on strike and they reached out to a competing company in China and made a deal with the Chinese executives where the Chinese company will send the strikers money via Bitcoin or something and in exchange the US workers will not show up at their jobs and the Chinese executives can short the US company's stocks and profit from their decreasing stock prices from the strike. Could the law stop people from doing something like this?
