Mathematical finance as a field has gone down a deep, dark, weird rabbit hole. The point of papers in the field is rarely to make a statement about how to invest, or how markets work. The point is to do a load of funky maths, showing off how clever you are, and then claim a tenuous link to finance. If anyone doubts what I'm saying, they should look up the definition of "No free lunch with vanishing risk" [1] and tell me how it relates to the real world.
