From the conclusion:
"With the Book of Abraham now confirmed as a perhaps well-meaning, but erroneous invention by Joseph Smith, the LDS church may well devote some reflection to the status of the text. The former Reorganized Church of Jesus Christ of Latter Day Saints, since 2001 renamed the Community of Christ, avoids this issue by treating the Book of Abraham as speculative writing by Smith, not as a document of historical truth. In this decision they are clearly correct. Despite its inauthenticity as a genuine historical narrative, the Book of Abraham remains a valuable witness to early American religious history and to the recourse to ancient texts as sources of modern religious faith and speculation. The book still has its uses and significance, but not for the ancient world of Egypt and Abraham"

Exactly.

Its use is as Biblical fan fiction inspired by possession of mummy afterlife passports.
