You're right fundamentally, but I also share OP's frustration in this concept that, especially with tech, it all just seems based on vibes now.

Also nothing will not be produced, if nobody is paid to produce it. Consumers lose their jobs, and have no money to buy the Thing -> the company that makes the Thing collapses -> the companies that made and transportet the materials for the Thing collapse. And all the people in the chain will have lost their jobs, and no money, so the companies will fall like dominoes... and nobody makes the Thing anymore. If money stops flowing, the economy stops working, and if it collapses, billionaires are the ones who will lose what they have, if stock market is no more.

Do these morons think, that millions of people would just sit quietly? Many countries might take some drastic measures before that total crash, confiscate companies and all that. Not every country is yet a fully fascist police state afterall, and all their rich ones will want to keep their power anyway. Running into a bunker will do jackshit, since the collapse is going to look very different from just some sudden apocalyptic scene from a movie.
