It's a bad practice. If nothing unexpected happens it's neither a good
nor bad "thing", but logging in as root increases the chances that bad
things can happen considerably. If there's no pressing reason to do so,
plain vanilla common sense dictates it's something you should avoid.

I've been driving a car for a lot longer than that and haven't been
killed in an auto accident either. The only thing that means is
statistically I'm more due for a flaming exit than I was 30-some odd
years ago.

No. Use sudo or it's *sudo graphical cousins when you have "things to
do". Su to root only when there's no other way. Those scenarios do
exist, but they're so few and far between I'd wager the average user
will never be in one.

For some people I'd wager this is even worse than logging into a full
blown GUI as root. Especially converts who might be use to doing things
100% graphically. It's the difference between handing someone a gun
they're familiar and practiced with, and one they're not. They're far
more likely to come away with self inflicted holes while flailing about
in unknown waters with a loaded weapon.

A password that does not exist is *impossible* to crack. I use
exceptionally long "random pronounceable" phrases strategically salted
with numbers and symbols everywhere possible. My pass phrases are quite
literally stronger than the underlying encryption they guard in some
cases.

It's still not as secure as simply locking or never enabling the root
password in the first place...
