I think I should have been clear. It does not make Unix single user machine but it is more useful for cases where a single user is the main user of a machine like the laptop user.
My reasoning was very simple. Nixos makes it easy to install packages on a per user basis. This would mean there is a lot of redundancy if another user also needs the same package. A snapshot/dedup filesystem will easily solve the problem.
