I'd say when the China issue gets very bad I would do just that! Fuck them and fuck the rest of the world. What are they going to do? For decades the west and east have been taking advantage of the US.
BTW, japan's deficit percentage of their GDP is worse than the US. They can follow suit. Hell, Russia did it...I would do this and local(US) bondholders could get some tax benefits, the outside world- Fuck them.
Of course, markets would crash, all sorts of havoc would spread like wildfire but from the ashes, the cleansed US would arise like a phoenix but of course, we would have to kill all the cadres of politkos who got us in this mess in the first place, reinstate the gold standard. That would happen somehow in the midst of the calamities that followed.
