A common main path, versus different main paths is not really relevant. That's because a common path implies branching separate ways into separate sub-paths depending on Law, when decisions and outputs are specific and different for each Law, which ultimately is sort of equivalent. This type of sub-path, which be then the object of the considerations made in this discussion, is still technically a different path, even if a short one. In cases when outputs are similar, the branching/separation may be followed by a rejoining a common path.
The more protection you lose, the closer you get to normal law.
Huh? Do I misread this, or is a typo?
The more protections you lose the closer you are to direct law.
