The Tumlinson book framing is spot on, space expansion isnt just about resources or survival, its about existential purpose. That distinction between practical spreadsheet arguments and capital-P Purpose actually matters more than most space advocates admit. I've seen too many pitches that lean on economic ROI when the real driver is fundamentaly about becoming something bigger than planetary constraints allow.
This is the real driver for people like you and me, and it does matter a lot indeed, but we still need the spreadsheet arguments to persuade those who don't see it. One needs to use different points foor different audiences.
