I'm a bit surprised how under-the-radar this story is in the mainstream press. It doesn't seem un-thinkable at all that in 5-10 years, countries will have digital borders to block certain countries from participating in their subset of the Internet. There's no way a Trump or Trump-like figure wouldn't love the ability to digitally block an entire country at their whim (like how he is doing with tariff rates now). And unlike a decade ago, it will be sold to the citizens with not much effort at all, especially if the current wave of protectionism/nationalism continues to hold.
