Usually when fraud is involved, people don't care about justice, they care about getting their money back, which means often the less legally competent party (who are often victims themselves) have to pay up, and good luck getting your money back.

The story sounds like CashApp didn't do proper KYC, so they should be held liable. Also I very much doubt that someone built up a sophisticated operation just for 1 victim, so there must be others. Why doesn't the police connect the dots?
