Law is based on a common consensus of morality (at least in theory) so they are, in fact deeply intertwined.
I don’t think that’s true. Maybe in its infancy law really looks like that, but as societies grow their law books get more complex and can very easily become separated from majority perception of morality. Does morality explain zoning laws, or is it more about the equilibrium point of a pluralist conflict, everyone looking out for their interests, etc.
Roughly. But always read between the lines and follow the money. We didn't selectively ban Tiktok because government finally woke up to the dangers of social media.
