I think it makes more sense to say culture is downstream from power. Culture includes the application of and (non-)acquiescence to law. Enshrining laws is important but only temporary if you don't seize and hold power. For the forces in power, the law is what they say it is. (hmm, I suppose if that means law=power then never mind)
This has nothing to do with what you said, just something I thought about the other day.

Power is more appropriate.
Law is the codification of formal power. Or something similar, there is probably a better formulation.
