I'm in the U.S. and I still have to click all those super annoying "Accept using a cookie" popups everywhere. So that EU law certainly does affect me a U.S. citizen interacting with U.S. companies.
The only ones you have to blame for that, are the companies to show you those annoying popups. They have no obligation whatsoever to show that to anyone outside the EU.
Start complaining to those companies and stop pointing your finger in the wrong direction.
To nitpick, while for non-EU companies GDPR applies to individuals in EU (and their data) as per GDPR article 3.2, any EU companies have to apply this for all personal data as per GDPR article 3.1.
So while foreign companies can decide whether they want to apply their GDPR policies (which generally should not require "cookie banners", though it is a popular choice) only to people in EU or all their users, an EU company does not have a choice, they have the obligation to treat personal data of Americans and Iranians and everyone else in a GDPR-appropriate manner.
