I don't know, I read the interview and it honestly wasn't clear what he was saying. He never mentions any particular policy that should be enacted (other than tariffs against other countries that don't follow our lead), and the interviewer doesn't seem interested, opting instead to ask questions about cosmology. It's a bizarre interview. His issue seems to be mostly with overconsumption of resources. But instead of creating a sustainable economy that can achieve growth through other areas (increased efficiency, increased use of renewable resources), he instead comes out against any growth and advocates a steady-state economy. But again, no specifics, just vague generalities and digressions into cosmology (arguing that economics should take into account religious questions).

I was honestly shocked by the low quality of the interview. If this was presented as an exchange between teenagers on Reddit, I would have believed it.
