There's a reason most people in well-banked countries use plastic over cash these days, convenience and consumer protection are it; and even with cash, the barrier to entry for fraud is higher since at some point that cash will come into contact with the banking world, and will have to be accounted for. If your cash flow is suspicious enough, it'll be audited.

Or less snarky: it's simply harder to steal something or defraud someone in meatspace than in the Internet, so less protection should be necessary.
