Probably depends a bit what example you're looking at. Iceland has a very traditional name system which is enforced. I think the idea is basically that names won't evolve so they can preserve tradition. Sweden on the other hand has a pretty vague "name can't be likely to cause child psychological harm" law, that doesn't really come into play unless you try to name your child something really outside the mainstream (there was a case a while back where a couple wanted to call their daughter "Metallica". I can't remember how that ended up going). I don't see how the Swedish-style system would stop names evolving. There are still plenty of trends and new names that come and go just like in the US. I doubt extreme name choices like Elon's "x-ash-12" would inspire a whole bunch of children to be called that.
