This sounds nice for someone in a developed country who has all they need, and is only satisfying their wants. But for most of the world, economic development is a necessity and a lifesaver. Child mortality is reduced, life expectancy and education level increased, child labor decreased, as a country's economy grows. This is not a fringe right-wing idea. This is the very real effect of economic growth in developing countries, i.e. most of the world.

Degrowthers often seem to forget that applying their ideas will literally kill millions in developing countries, by preventing the economic developments that would have saved them.

FWIW, I am not a fan of unbridled capitalism either but think that it is important to consider science in important matters like this and not just go with gut feeling. That applies to both fascism and degrowth.
