The whole thread is TL;DR for me, so maybe someone else answered this, but:

Fucking YES. After all, what the fuck has the Bitcoin community built if the only thing stopping it from being trashed by a large national interest, is disinterest on their part? Absolutely nothing, that's what.

If a large nation with huge resources decided to take an interest in toying with Bitcoin, that'd be awesome. We can put our imaginary money where our mouths are. We can see how the devs, miners and community in general respond to a massive difficulty roller-coaster. No matter what happens, Bitcoin would be better for it.

So if (and what little of the thread I've bothered to wade through, it doesn't seem likely) a large portion of China did decide to fuck with Bitcoin, absolutely - go right ahead.
