What would a nation state level attack look like? If they took over the network, it wouldn't really give them anything useful. If they took all the bitcoins, the value would plummet rapidly towards zero, unless they were willing to prop it up with their own currency.
Easier to just tax the crap out of BTC. i.e. any BTC mining done in this country owes us 80% of their BTC mining rewards.. etc.
If China did that, and they are currently doing some 60+% of the mining... it would change the incentives for mining BTC in China drastically, but China would make some sweet cash for a while, and eventually effectively ban BTC in China.
Rinse repeat in other countries, if they decide to hate on BTC.
Though really, I don't see any country wanting to do that right now. They are having too much fun watching who is transacting on BTC thinking they are hiding their transactions from the govt(which they aren't).
