Law Minimalism
However, when we extend this idea to exit game, even exit game seems like useless in front of law-enforcement.
Here we need clarification.
The law-enforcement is powerful but slow and uncertain, so its usuage should be minimized.
This is just a design tendency and so you can use law-enforcement over #repeatedgame in anywhere you want. From my (sg.icon) point of view, the amount of trusted money is quite sensitive in the financial law area. And so exit game is the biggest virtue of Plasma, with an advantage that Plasma never has to trust any fund in its construction.
So, I would love to use this powerful law-enforcement only for EscrowTx to achieve Fast Finality of expressive contracts.
