The idea that capitalism should go to a point and then be stopped is a pretty standard one from Marx. He greatly admired capitalism but believed once it made people rich it would no longer be needed and the workers would naturally take over through revolution. That’s not to say you’re wrong just because you agree with Marx, but rather you should consider why you are so attached to this idea. Marx’s ideas are a type of religion dressed up to look scientific via “historical materialism”. It’s appealing to believe that time is under humanity’s control rather than something outside of humanity, but there’s strong reasons to believe that is false (the universe will last much longer than humans will).
