There is a way to get into the Spanish bureaucracy quite painlessly! Its NIE blanco. You can get it in any Spanish embassy, before even getting to Spain. With that you can create a bank account or job hunt.
That won’t work entirely.
The NIE blanco is a PDF so it does reduce complexity later as you have a number predefined.
But many services and people might ask you to show physical NIE. And also without address you’ll be able to open a foreigner bank account which is different than local.
