Here is the referenced Bitcoin Magazine article: https://bitcoinmagazine.com/business/bitcoin-mining-concentration-in-america

I agree that hashpower overly concentrated in one jurisidiction is a threat. But I'm not sure this is a result of patriotism, as the article implies. Probably USA just has cheaper power than Europe and laxer regulations compared to most other countries.

Some of scenarios laid out in the article, like a fully deanonymized permissioned network, would probably result in a hard fork.

This is true and you know when I mentioned a lot of the hash rate is in Kazakhstan to my co-worker, he said "Well that's under Russian control" and I was like yeah but it doesn't mean that Russia controls it and the hash rate that's in the US doesn't mean the US controls it either, but this lack of understanding of how Bitcoin works is like, if the US does not control it then some other country must control it and that's a threat to the US and that just isn't the case at all.

Now, on the other hand, its kinda nice that 51% of the hash power isn't in China anymore XD
