The writer overlooks some very important points. In some areas there may be no other business to serve customers. Then again, if a business is serving the public, public accommodation laws, both local and federal, take effect. Further, if we allow personal beliefs to override public accommodation laws, then we must allow all personal beliefs: so an individual at the DMV might deny women drivers' licenses if they believe women should not drive; another might deny service to blacks or Christians with the same claim.
