The idea is that everyone locks up more value than they can potentially win by cheating. So every side is egoistically interested in getting their money back, so they have to find a compromise. Trolling people at your own expense is possible, but I expect it to happen infrequently to not be a big concern (just like vandalism does not happen everywhere all the time, but only somewhere, some of the time; plus in this case vandalism is quite pricey).
Many people discuss extortion scenario, so let me reply to all of you. Extortion is limited when both parties are anonymous or have little knowledge about personality of another person. If I try to play dirty with you, how do I know that you are in a desperate position and will submit? Maybe you will turn out a better player in this poker? Or maybe you will simply send me a message "no, please pay as we agreed initially, period" and we won't be able to discuss this longer.
This Nash Equilibrium approach is particularly great for automated agents. E.g. two apps paying each other for measurable service and owners of both apps know perfectly well how another app will behave - there's no one to extort. Either you follow the contract, or you don't. So you can troll someone by simply losing your own funds, all alone in a sad silence.
