For sure. They mention in the video that the soil would have to be washed. Which they mentioned is entirely possible and wouldn't be too expensive. I believe JMG makes a point that the most "expensive" part of it would be long-term inhabitance. We just really don't know how zero-gravity would affect birth, fertility, etc. Typical reproduction might not be possible.

I think a lot of people in this instance think space travel is prohibitively expensive. It is, for interstellar excursions. We also have a bad taste in our mouth simply from King Bazinga and his bullshit and the current state of capitalism that doesn't actually incentivize anything about space travel other than profit.

Here is someone who was an actual scientist-turned sci-fi writer who works with the constraints of reality and doesn't hand-wave or speculate based on "bazinga-tech" but research done by NASA and the ESA.
