The ironic joke, is that the ability to buy many electronic components and modules at very low cost, such as $1.50. Means that younger, upcoming American, Electronics hobbyist can/could, with their limited $availability. Learn electronics, and potentially be future engineers.
So in some respects, you are shooting yourselves in the foot.
Also, Chinese custom PCBs, will probably be hit. Because the cheapest shipping options, may disappear or cost a lot more.
Maybe this will not be so bad in practice. Just that the postage costs will be much higher, which is only fair, really. The China thing was exploiting a loophole, in practice. Even though it was legal.
