You are wrong, again.

Passwordless root SSH is perfectly fine, which is why it is enabled by default. By people who have thought a little longer and harder about all this than you. (Sorry for the tone. Maladvice like yours on public forums is demonstrably harmful.)

No offense taken, I am all for a strong opinion (as opposed to a bland one trying not to offend anyone at all). I will re-examine my assumptions; any specifically relevant links you would recommend?
