Honestly, despite all your reasons, I do think the USD is probably the most stable currency in the world... purely because it's used in almost all international trade. BRICS is the exception, obviously, but all the other countries combined still provide a ton of stability. Don't forget China devalued the Yuan in 2015. Totally open to changing this in 5-10 years if HBD is still around and things have changed dramatically, but if you want stability I think the USD is hard to beat.
