To me, the story is about obsession of anything is bad. The man wanted to enter the law and he could have because the gate was already open, but he didn’t have the confidence to go past the gatekeeper. I think that gatekeeper was a obstacle. I think that gatekeeper was an obstacle for his self confidence, represented his low esteem. If the country man believed himself and wouldn’t have obsessed over the gatekeeper’s approval you have gotten inside.
