[DUPLICATE POST, LOCKED] Rejected for Intellectual Property reasons. What's up?

Hey, good people. Little help, please.  I'm new and having a hard time understanding some of my rejects.  This says it's for intellectual property reasons.  I see other images of this archway at Jackson Hole, what's up?  Could it be because of my new-ness I'm not able to do editorial?  This archway has got to be public property.  Any explanation is appreciated.  

Thanks again,

Gary
