You don't have to believe in infinite growth, the problem with the model that makes the scary bit after the slopes change to down are all BS because of: "However, it is important to note that the connections in the model and the recalibration are only valid for the rising edge, as many of the variables and equations represented in the model are not physical but socio-economic. It is to be expected that the complex socio-economic relationships will be rearranged and reconnected in the event of a collapse. World3 holds the relationships between variables constant. Therefore it is not useful to draw further conclusions from the trajectory after the tipping points" That tells you this model disregards how every single societal crisis in the past was solved or at least mitigated: A massive change to the order of society (think germanic tribes conquering rome, magna carta type stuff, Napoleon et al taking France from a monarchy to an anarchy to an empire and, after calming down a bit, to a republic, etc. etc.).
