A lot of the stuff I am buying in China (electronic components and modules) either does not exists in US shops, or exists with very high markup (3x-5x). And even the stuff that is sold in the US is same Chinese parts, but imported by seller instead of me - so it gets more expensive as well.

I don't think this will give big advantage to US shops, it will mostly be extra expenses for consumers.

Surely you must realize that's a very atypical use case and is dwarfed by people buying cheap clothes and trinkets? Just go to aliexpress or temu right now and see what the items on the front page are. It's not niche components that you can only order from china, it's the same cheap shit you can order off amazon or buy at a local discount retailer.
