There is no such thing as a user 'node' (well, unless you use one of those modules). Users are just users.

If you get rid of /user, how are you ever going to get in to administer the site?

I have a bunch of sites where the login block has been disabled entirely. On those sites, one must use the /user path. I don't see what the harm of leaving that in place could be. Without an ID and password, the user is going nowhere.

Actually on my site it's 'user' not login. ('login' gives me "Page
Not Found") As it is now, I can create a page with the login block
that could be a secret name. But 'user' persists. I would really
like to disable the 'user' node, which is (I guess) kind of a
'builtin' node. I wonder if it could be disabled from the database.
What do you think?
