The purpose, of course, is to keep the banks from central Europe out of Sweden, and that includes N26 et. al. They have very little interest or ability to compete with them, neither in terms of fees nor UX. Fortification and minefields are therefore the best alternatives.
A few years ago, the CEO of a (then) new investment bank famously said that they will be the last bank created in Swedish history, due to the above.
So don't do that?
I think I still have a 'regular bank' account open, but I don't use it at all. Salary goes into Monzo, and payments go out. It's the only debit card in my wallet and that I use.
I didn't switch wholesale because I'm not fully convinced. I feel these new banks and bank-like offers will for some time search for a right fit and may change or disappear in the next few years.
Also, no-fees-abroad is a great feature, but perhaps not the 10x to spur (my) wholesale adoption.
Maybe I'm just not an early adopter (although I use them abroad, so in a way, I am).
