Whatever China pegs their currency to, it won't be stronger than that
Sorry, I have no idea what you mean by this.
If they peg the Yuan to the US dollar, it simply can't be a threat to the latter.
True. That is what they have been doing and they are now looking for an exit (or at least potential exit.)
If they peg it to gold, then more power to them. Most major currencies (like the already mentioned American dollar, Euro or Swiss franc) are by far more stable than gold (gold in comparison with them is as volatile as hell).
Pegging it to gold would be a declaration of war to the global elites. It might happen is China is pushed to far, but still not likely, from what I can see. A properly done pegging would mean the yuan becomes the most stable money, and would send a lot of global capital and demand to China (since initially the yuan would be very cheap, if they do it right.) Not good for the Western empire's (already shaky) stability!
In any case, it always makes sense for China (or any power not totally in bed with the global elites) to acquire more gold and Bitcoin.
The elites want us to believe gold is volatile and there is plenty of evidence of their manipulation of the gold and silver 'markets.' Still, over the 4 decades since gold was 'demonetized,' the dollar has lost 97% of its value against gold. I agree, gold is not for the short-term nervous, but it's a good long-term investment, in proper proportion to your other assets.
Other than that, you can't solve a problem by relying on people who created it. Should the Chinese authorities create their own GovCoin (that's what you started with), they will abuse it in absolutely the same way they abuse the Yuan right now
Which problem are you talking about?
That all state powers will abuse their issuance of any kind of money is a given. However, pegging the yuan to a ChinaCoin means that the limited-issuance structure of cryptocurrencies and the yuan becoming an IOU payable in a cryptocurrency will make the yuan structurally the soundest state currency in the world. That would not be too different from pegging to gold (as I described above.)
And, as I mentioned, the only way the Western elites can fight that eventuality is to support Bitcoin. So if China doesn't support Bitcoin, the West will (that is, unless and until China becomes a fully embraced ally of the West, which is probably not going to happen.)
In the final analysis, there really is something written in the stars that, in times of global disunity, non-state assets will gold and Bitcoin will do well, one way or another.
