Capitalism works well when there is plenty of potential for growth, but when there are non-monetary reasons (such as the literal end of ecosystems favorable to human life) that require adjustments or even degrowth, it quickly devolves into feudalism - and the problem is that we do not have the means to quickly stop CO2 emissions without tightening our belts in energy consumption, which in turn requires some degree of degrowth.
