Any set of rules has an exploitable architecture. Even the simplest. And in a situation where min/max is a value that can be optimized? Someone will do so, and they will profit by doing so.

That's an inevitability of systems. Orders of magnitude more if we are talking about "money," even money in the abstract. Just the idea of money will find people working very hard to get some of it. (Chinese gold farmers and World of Warcraft come to mind.)

We'll have to see how things shake out.
