> There are specific things like extradition treaties, trade agreements, and parallel legislation that cover existing areas where this happens. Is there one that covers application of the GDPR in the US?

Nope. Extradition only covers the case where you go to some other country and commit a crime there, then return to the US. If the crime you committed there is serious, and is also a crime here, then extradition can apply. There are other conditions as well, but the key is that it has to be a crime in both places.

Europeans can claim that you must follow their laws until they are blue in the face but it won’t magically become true. You can safely ignore it. Enjoy competing against European businesses without having to pay any of the same costs.

Even if you do not have to comply with GDPR, 12 States have passed data privacy regulations to date. You may still need to comply with data protection law regardless if you qualify for various State laws.

Even if State law doesn't apply - you have have HIPAA, GLBA, SOX etc.

All irrelevant to the question. But it of course true that we have plenty of our own laws to follow.
