Put down the Ayn Rand bong, please. I don't think any federated network in Internet history (and I'm including Usenet) ever had a need for some hypercomplex reputation/coinage/exchange... thing. You think this would be a great idea, fine, you do you. You could even fork the software if you wanted to see if you got anywhere. But I really don't think there's any traction whatever in this idea.
It's just in European. it's an entirely reasonable assumption that people in this continent with even a passing interest in the world will know what an NGO is (that's not even European-specific) as well as what the GDPR is. Your argument suggests that people from the US, for instance, should be forbidden from talking about IRAs and the IRS and their 401(k)s and the DMV because those terms mean very little to nothing over here.
