"Baggins" is from a Yorkshire dialect word for tea as a meal. Bilbo's way of life in the Shire, defined by features like the availability of tobacco and a postal service, would be English and middle class, and its period would be in the Victorian to Edwardian eras. This is not compatible with the much older world of Dwarves and Elves. Tolkien appears to have based Bilbo on the designer William Morris's travels in Iceland; Morris liked his home comforts but grew through his adventurous journeying. Bilbo's quest has been interpreted as a pilgrimage of grace, in which he grows in wisdom and virtue, and as a psychological journey towards wholeness.
