Define “accept”? If I, an American with an American phone, travel to China and can’t buy lunch because the American government mandated deplatforming of the payment app, that’s really annoying to me.
I agree that nobody in the US should be using the e-CNY in place of the USD, but a more targeted law could accomplish this without trying to police the applications I can install on my iPhone
I frankly doubt e-CNY even has a chance to take off here, in my local Chinatown everyone pays by credit card not by Alipay or Wepay.
Politicians only like hammers so all problems are nails, maybe you are right that the enforcement mechanism is overly broad but I also think the situation you paint is inaccurate/made to seem more difficult than it actually would be. My parents went to China and did fine paying for things 13 years before Digital Yuan was created, my (naive) assumption is that, like all places tourists are herded in any country, the place you go will accept both native currency and USD, watches, nice shoes, jewelry…
With the pandemic US has caught up a lot though
