What other banks do this in Europe (outside of Denmark)?
I don't think this policy is actually a problem for many people here. Most people above that limit either invest it, put it into a "savings deposit" (you agree to not touch the money for some pre-definied time and in exchange you get better, positive interest rates), or spread it out across multiple banks (since savings accounts are usually free, but only guaranteed up to €100K when the bank fails).
