You're claiming that the wealthy don't value their money enough to commit crimes for them, while knowing that they value their sex drives enough to do so. I don't see how this is a tenable position.
People routinely commit crimes for money, rich and poor alike, often for relatively irrelevant sums - and very often for money they don't even have yet. The incentive to commit crimes to prevent losses is even higher, given the well established loss aversion bias in all people.
And we don't even have to discuss losses. Many people commit crimes to get money quickly, from murder to insider trading to insurance fraud. If you agree that many people would be willing to kill for a few thousand or million dollars, you have to admit they'd be willing to threaten and blackmail a newspaper editor or production crew to try to fix a bet - especially when the internet brings them anonimity, and even if they bet a small sum that they wouldn't even care to lose.
If you don't believe this, try to go to a betting place in a poorer area and offer 1000:1 odds that no one punches you in the face hard enough to break your nose (a crime which could easily land whoever does this in prison). According to you, as long as you don't allow anyone to bet more than, say, $1 on this, it should be a very safe bet for you, surely no one would be insane to risk prison time for losing just $1, right?
