MitID and NemID before it was pretty much bought by the Banks and the government together.

It is to avoid the banks needing their own id for customers, as people would need to go into the banks using their passports etc to register.

Some banks do have their own logins and IDs for various purposes, but you often need MitID somewhere in there simply to verify the actual identity of the person with the account. All the other logins simply give you access to the ID it doesn't actually verify it. MitID does that.

For example Lunar doesn't need MitID during 3D Secure (online payments), but that is only because you used MitID at some point to store your proof on your phone, that you can unlock with a secure enough method, and then do the payment. This is considered enough, as you still use an identity that has been verified by MitID at some point.
