Substitute "most European countries" with "most Bundes of Bundesrepublik Deutschland" and you will be closer to the truth. Otherwise, I'd rather doubt it. To say it bluntly, Europe != Germany
One thing is right though, many Germans think they are unique on this.
To me it appears those are somehow related to what I mentioned on my comment, "Those that only sell bread and nothing else, are very few and slowly going away."
On the other side of the border, most of those bakeries survive in small villages with an aging population, and have been wipedout by pasteleria/panaderia businesses in towns and cities.
Then again, I never been in tourist free areas when in Spain.
