Is there any country in Europe where you can't naturalize after 10 years? Maybe some micro state?

My point is, if you're not willing to go through the naturalisation process when you're eligible, what's the problem?

I agree with your point - but to answer your question, none that take _more_ than 10 years but quite a few that take 10 years. Austria had particularly tough requirements - 10 years, language competency _and_ no dual citizenship
