Not really! The EU simply claims jurisdiction over any company that trades in the EU. The company doesn't have to be a "web property" - if you sell cars, or food, or medcines in the EU, you have to accept EU jurisdiction. If you want to operate a web property that is accessible in the EU, that's fine; but don't have a EU trading arm if your web property isn't GDPR-compliant.
