That list doesn’t actually impress me much if any, and the conclusion at the end is certainly a blanket statement with no basis in reality.
We have one used, 20-yo. car. We live in a 800 sq.ft. house. We cook well over 90 % of our food at home, and eat out maybe three times a year. I wear all my clothes until they basically drop off my body, and we mend them regularly until that time. Vacation time means driving to national parks or visiting relatives.
We do use the internet daily, although I don’t use the smartphone for other than calling and texting.
We like living like this, and know dozens of people who do likewise.
