I stand corrected, saw your other post about sammordningsnummer, and googled that. It's quite the corner case that I'd never heard of before.
I'll agree that the system is not optimal and could be better in this regard, but it is hardly dystopian. You have about 2 hoops to jump through to get your ID, and after that you'll have full access to one of the most convenient bureaucracies on earth (and that's probably the first time I've used the words convenient and bureaucracy in the same sentence!)
Having lived in a few different countries, and having friends who have migrated from a few others to Sweden, I'm fairly confident the Swedish bureaucracy is ahead of the curve.
If I may ask, where do you live that has a better system? How does it work over there?
Yes, there are Swedish citizens without personal numbers. Not only that, but you can only get a personal number if you have been a resident. If you are a Swedish citizen who has never lived in Sweden, you have to move there to get one. Otherwise when you are registered with the tax authority abroad you are only issued a samordningsnummer.
The difference between the Swedish personnummer and similar system in other countries is basically that the Swedish version functions unusually well.
You can actually get a personnummer without being a citizen.
