In my opinion, the USD you see on the screen is backed by a treasury, gold, or bitcoin, it's kinda the same thing, it's just an abstract metric people have attached themselves to because they use it so much to judge how much time it would cost to acquire goods and services.
To try and break that network effect and inertia takes time. In my country we switched from the British Pound to South African Rand, today people don't even think about it, many don't even know it, but to my grandparents generation, it was a massive transition that changed a lot of things for them.
I just see it as that but on a global stage and everyone will go at their own pace while others will die denying the change
