I have a lot of personal theories how my country can best cope with future geopolitical adjustments. If I were in charge, the first thing I would do would be to close most foreign military bases. We can have the strongest military in the world and have them largely based in the US. I think the US Navy continues to be a good investment, but I would cut back a small amount on intel and other military branches.
All these ideas of some kind of blockchain based common alternative is still just a pipe dream. You can’t base a real currency on crypto. If you think you can you don’t understand what currency actually is (hint: currency has never been a successor to metal/coin based transactions… it’s an abstraction over debt and debt has and will always be the main way value is exchanged. crypto cant replace debt based currency because debt is based on trust in humans, something that trust in an algorithm can’t replace)
