Hi Robert,

Thanks for the well thought comment and the kind words about my writing. Glad to have you as a reader, I look forward to more discussion on future topics.

I agree with the other indirect costs you outline here. I’ll do a bit of research to see if I can find any papers that have tried to put a price tag on those costs. If I can find it, I’ll make an edit to the article and include those figures.

Thanks again!

Ben
