Full Idea
One way to get the conclusion that laws are necessary is to combine my view of properties with the view of Armstrong, Dretske and Tooley, that laws are, or assert, relations between properties.
Gist of Idea
We might say laws are necessary by combining causal properties with Armstrong-Dretske-Tooley laws

A Reaction
This is interesting, because Armstrong in particular wants the necessity to arise from relations between properties as universals, but if we define properties causally, and make them necessary, we might get the same result without universals.
