I think it's faulty logic to assume everyone who would benefit from Laura's work already knows of it. Considering how many people are slowly coming to an awareness of dietary issues, let alone our pathological world, seeking in general will only grow. However, disinformation efforts continue to grow as well. Therefore, in the sea of competing information, expanding access through other channels helps the message break through the noise.
In my mind, there is a benefit to expanding access. The only questions that need to be answered pertain to the size of the potential audience, the percentage of those who will read such information, the percentage of them who would benefit from reading it and the costs to deliver it.
My initial thought would be to use books already available for free, which minimizes loss to sales (since Laura deserves every penny she can make). This would increase her reputation as an author within circles currently unfamiliar with her work and would help promote Horns of Moses.
My $0.02 for what it's worth,
