Definitely people will still consume stuff, but they’ll limit themselves to the things they truly need and may even have higher quality standards.
In the fiat mindset people constantly consume low quality junk and that’s exactly how corporations want it to be. That’s why the word is utterly polluted with ads, to make you buy useless shit you don’t need.
There’s a big difference between healthy consumption and compulsive, profit driven consumption. This would be a foundational change to society and to individuals, and I don’t think corporations want that.
