But today that does not happen, so given how people like this are punished today, what is the correct financial penalty? In general threats and stalking are only meaningfully punished when brought up during sentencing for subsequent assault. However it's worth noting when thinking about how "unreasonable" a financial penalty is, that all your future employment options get severely limited. 500k over a lifetime of employment is in the region of 10-15k/year, you can hopefully see how the financial cost of a criminal conviction can easily dwarf these costs. Obviously the impact of a conviction is incredibly variable and filled with all sorts of bias - the financial penalty of a record is lower if you're rich than if you're poor, or social status, race, etc. But in general I would guess any meaningful criminal penalty would easily have a lifetime financial cost of more than 500k.
