Do any of those reasons weigh against measuring the seriousness of financial crimes in terms of actuarial lives? No problem with the objection that lives are priceless, but couldn’t the inverse still be a useful lens?
I dont think it is useful at all. They are categorically different. There is single plunishment for lives lost in the legal system either. It depends on many things like intent. A life lost could range from life in prison to no punishment at all. Same for financial crime, and each depend on like 10 factors.
