"Should users be able to 'chown' their files?"

No.  What about a program which checks the ownership of a shell command file,
and then runs setuid to the owner?  This is how at least one version of 'at'
works.  A user could easily create a root shell if he/she were allowed to chown
the command file in /usr/spool/at.  I know of at least one site which has had
this happen.
