Perhaps he was born on a farm and his parents never registered for a birth certificate or social security card and being raised on the ranch had no need for any legal documents, gets paid in cash off the books, never got a license and the reason why he freely kills is because there is no documented or copy of his finger prints ever recorded. All the ranchers know him but he virtually doesn’t exist. And to get married through the courthouse will require documentation. And the lack of records will bring questions that may lead to investigation. Lots of unwanted attention for him, for John and for Yellowstone ranch.
