> The best way to put pressure on the Chinese Communist Party and help pro-democracy voices in Hong Kong (and the reduce Uygher genocide) is to avoid buying Made in China goods where possible.

Decoupling could be helpful on several fronts, but it's not going to happen via individualist boycotts. Those are useless, and just too many things are made in China without realistic alternatives. If it's going to happen, it'll be through increasing tariffs (preferably slowly over time) and other government policy.
