For awhile there was a "hack" to actually get the dutch Amex (and/or possibly the FB branded one, I can't really remeber the specifics). But the "hack" was to sign up for a "dutch" bankaccount via one of their hybrid e-banks. Because the only hurdle to overcome with dutch Amex was to authorize automatic payments of the bill (which could only be done with local account). The account was possible to get as a EU-citizen regardless of recidency, and then Amex would issue a card based on your credit limit on your domestic card.
Or something like that. But it was possible
Especially with Amex it is annoying you cannot get another EU country's card, as they have different partners in each country. Even MR partners differs vastly - in Sweden only a very limited selection of Airline transfer partners exists, basically the avios-crowd, Finnair and SAS.
