All I'm not advocating writing off the justice & arbitration system completely. What I'd like to see is clear distinction between those two categories (as they serve different use cases) and applying the justice system only in very precisely defined cases. Rescuing people from theft is very tricky, especially when the ultimate judges (i.e. the top BPs) have disproportionate power and normal shareholders stand no chance against them.
Thus the primary thing the Constitution should do is define clear limits to the power of BPs instead of stating that all shareholders are effectively subject to justice served by them.
