At the beginning, some people saw that the government was making huge profits, so they started to have some ideas. They captured the mice without killing or selling them, and instead organized mouse fights privately.
As mentioned before, only the officials can obtain what's needed to make the Mad Mouse fight, this is called the core technology.
You can make the mice fight when they're starved, but it won't last. Some males and females start mating, which is just absurd. The audience won't buy it and might even report you, because there's a reward for gambling whistle-blowers.
If you don't gamble, the Lord doesn't care. But if you do, it's like reaching into the Lord's pocket for money. Better go build roads instead.
But how to make money without gambling? It's truly a conundrum.
