Article 13 is for copyright owners, not individuals. Large corporations benefit the most from this legislation.
Also, if I'm reading it right, one of the provisions Article 27) is that if you are outside the EU, you need to hire someone inside the EU as a representative / contact point for GDPR issues. If I'm running a one-man business, there is no way that can happen.
The reason I'm concerned is that if I start a business providing support for one of my open source products, and have something like a web forum, well then I have user-generated content, so that would mean that I have to now hire someone in the EU to act as a point of contact.
You still have to follow the majority of the Article but a representative is not required.
And enforce this how? You get arrested upon setting foot in the EU when failing to do so? This would only work in Germany and maybe France. The EU doesn't have its own police, they rely on states cooperating. This is why Puigdemont is free to move in the EU (except Spain and Germany where he was arrested), despite of an arrest warrant issued in Spain.
