I'd argue that no other thing, apart from information, is transported as easily as electricity, once the grid exists. Sure, there are capacity limits, but I doubt that shutting down crypto mining would cause problems to the grid.
I recently read that some are thinking about connecting the US with Europe via DC cabling.
Here's a related, old article: "Submarine power cable between Europe and North America: A techno-economic analysis" (2018)
• Developed a 2030 power dispatch model of Europe and North America (NA).
• Identified socio-economic benefits of European-NA electricity trading through a HVDC cable.
• A 4000 MW cable increases social welfare by 177 M€ on an annual basis.
• This benefit for society is sufficient to cover the investment costs.
