To delete a directory a user must have an appropriate permissions to a
higher-level directory.

Taking your example literally:

root@x:/# mkdir /dir
root@x:/# chown user /dir
root@x:/# su - user
user@x:~$ rmdir /dir
rmdir: failed to remove '/dir': Permission denied

Why it behaves so? Because this:

# ls -lad /
drwxr-xr-x 23 root root 4096 Jan  6 15:33 /
