Run an adblocker. The Web was a total mess even before GDPR came along and not limited to Europe. If the issue of denying sites a revenue stream bothers you then perhaps make yourself a promise that you'll turn it off when ad networks stop being a vector for malware and/or stop engaging in the un-permitted collection and sale/abuse of personal data.

Personally, I run NoScript (as well as ad blockers) and so cookie popups are relatively rare on my Mac, but I still get them on iOS. I don't like them, but I see them as a warning that the site is going to try to exploit my personal data in return for serving me content.

It's also worth pointing out that there is no actual need to have a cookie banner unless you're doing something with the data that actually needs permission. For instance basecamp.com was GDPR/ePrivacy directive compliant when I was there, but never needed a banner because they decided to stop collecting and processing personal data in a way that required permission.
