I find that the real world works much like Bitcoin in a sense that one could use his mining rigs to double spend and scam for BTC, but it gives little to no financial compensation in comparison to mining in an honest manner.
Same principle applies to scams, even the biggest Bitcoin scams have profited relatively little (and at a high legal price) to the perpetrators in comparison to what they could have made if they applied their skills at operating in an honest manner.
Mircea sums it up nicely.
