Wouldn’t Lucy and Emma be the most likely people to know whether or not Joseph Smith could have written the Book of Mormon?

Statements from those closest to Joseph Smith confirm they did not believe he could have written the Book of Mormon himself. Interestingly, his mother and wife both believed he could not, and did not, write the Book of Mormon.

His mother said (when challenged):

Let me tell you boldly, that that book contains the everlasting Gospel, and it was written for the salvation of your soul, by the gift and power of the Holy Ghost
– Jones, Emma and Lucy, 83.

And his wife Emma said:

“Joseph Smith … could neither write nor dictate a coherent and well-worded letter; let alone dictating a book like the Book of Mormon. And, though I was an active participant in the scenes that transpired, it is marvelous to me, ‘a marvel and a wonder,’ as much so as to any one else.”
– Last Testimony of Sister Emma,” Saints’ Herald, 1 Oct. 1879, p. 290

Why would we know better than Joseph’s mother and wife as to whether he could, and did, write the Book of Mormon?
