when linspire has the user login as root everyone screamed about how stupid it was, that they should have setup sudo instead
now ubuntu (among other distros) setup sudo instead and people scream about it not being safe.
what exactly should a distro do? force every user to logout and login as root? we know that that's not a good idea, windows tried the equivalent and the result was that everyone ran as 'administrator' (root equivalent) all the time.
