By the way, I've lived in a few European countries and researched many others. The Netherlands was by far the easiest/most efficient in terms of bureaucracy.
If only. Instead you run in to catch-22s and simply get a shrug and "it's not possible".
The big downside of being the "easiest/most efficient" is that it deals with exceptions poorly; once you fall outside of the "efficient" workflow you're screwed. Lots of people run in to problems with this and people literally become homeless because of this. Ironically, it's easier if you're actually homeless and sleeping on the street – as opposed to being homeless and having enough money to stay at hotels or are temporarily staying with friends – as there are some special exceptions for people registered at the salvation army and such.
Anybody with > 100K euros in income from consultancy (which should be most of them!) living in NL should consider doing the same thing. There is some overhead but that's easily farmed out to an administrator.
As far as I can compare with some immigrant friends in the Netherlands I feel Swedish bureaucracy is on the same level or even less burdensome than the Dutch one.
