Third, much law in the modern world governs mundane, trivial matters that could be regulated in any of a number of ways. It is simply implausible that the thousands of minute regulations applicable to daily life are rooted in God’s will or the nature of the universe. Naturalism thus provides an unconvincing justification for the content of much of contemporary law.
I recognise that God probably cares more about serious matters than 'minute regulations' (eg: complex tax codes, which (one would prefer to think) God would simplify), but the use of the adverb simply feels too unconditional and biased to me; I do not understand why it is simply implausible that determinism determines law.
Am I correct that the above quotation presupposes 100% free will, and rejects entirely determinism? Or did I neglect something that makes the above evident even for Free Willers (ie: Libertarians)?
