mount - 14.04: login loops back on itself - ecryptfs

This problem follows on from
14.04: No Auto login at User Account settings - I am administrator (see all comments)

I tried to remove encryption via this link How can I enable autologin for my user account when the option is not there?

but when I tried:

$ mv -rf /home/user
mv: invalid option -- 'r'

after that I was getting cannot remove [etc...] Read Only file system.

I skipped over what couldn't be done and went straight to trying to rm /home/user/.ecryptfs. Finished, rebooted, and now the login screen is stuck on the password login screen

I went here and tried this Login screen loops unless you login as Guest

I inputted command sudo mv .Xauthority .XauthorityBak which resulted in

mv: cannot stat 'X.authority': No such file or directory

I tried

$ mount -rw -o remount /home/[username]
mount: only root can do that

I tried the second answer here Ubuntu gets stuck in a login loop

$ ls -lah
