There is a semi-practical use for this information: these are the absolute minimum tech trees required to spin off an independent off-planet habitat (whether in vacuum or on another planet).
If you're a hecto-billionaire / trillionaire however, this is also the information you'd want to be assured you can try whatever harebrained scheme you want and if it breaks the world, you externalize all that harm and "reboot" the world in your own image with this information. It would be bad if someone really buys that line; I don't think it is possible without a lot of testing on a vast scale, aka trying it out for real in say, space. Good thing the only working example we have of this kind of "booting" is history, and it seems to take way more than a $trillion to run the "bootstrap firmware" to a self-sustaining civilization at around say, 1940's tech tree level. I estimate around 70-100M people+children at the beginning, 30-40 years before you're out of bootstrap phase.
