You're not going to die, so why is it a bad idea?

This was rigged by an instructor, this school no longer requires certification.  Is a clove hitch safe? Often, but it isn't bombproof when it is out of sight. Any added links in the belay chain introduce risk. There is plenty of beefy static to tie to this tree, the 8MM cordalette and single carabiner are not needed, so they are an unnecessary risk. "But it is one of two anchors." All anchors should be bombproof, full stop, no exceptions, ever.
