I do not know about Nordic countries, but in Germany, the Aufenthaltstitel is NOT a valid ID by itself even though it has everything that any other national ID would have. So, if asked for an ID in Germany (especially by the agents of the state), this e-residence permit will not get you far. I believe the same practice exists in NPU countries as well.
