Say the entire country of America bans 3d printers without DRM, why would a German 3D printing enthusiast stop developing their firmware?

Note that I’m not saying these bans aren’t bad. They certainly can and will cause harm to the community as a whole. But I don’t see the argument of, “if it gets banned in x place, it goes away forever, for everyone”. There are thousands of projects that are already illegal and exist without issue online. Piracy is illegal but still easily doable, it’s already illegal in several states to 3D print certain gun parts but people still create the files and print them out.
