The GDPR doesn't try to remove anything from the global internet. You're free to not serve your site in the EU. Texas is free to block sites in Texas. But Texas trying to remove the ability of Europeans to access European websites is a completely different matter.
> The GDPR doesn't try to remove anything from the global internet
GDPR Article 17 expressly requires the removal of things from the global internet
> You're free to not serve your site in the EU
Geoblocking is functionally impossible
"But Texas trying to remove the ability of (for instance) Europeans to access websites is a completely different matter."
I fail to see the difference in principle from the federal government doing this for copyright violations.
