It is not the case that If the laws of nature are necessary, the melting point of gold is necessary in the same way that gold's atomic number is necessary.

Reasons For
2 perspectives
Reason for 1 of 2
?
1.
Laws of nature are contingent regularities, not metaphysical necessities—a position defended by Humeans like Lewis via Best System Analysis.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
If laws are contingent, nomic consequences of a kind's essence inherit only nomological, not metaphysical, necessity.

How convincing is this?
Think about whether this reason is strong or weak
3.
Therefore, gold's melting point could differ in worlds with different laws, unlike its atomic number, which is fixed by constitution alone.

Reason for 2 of 2
?
1.
Atomic number is an intrinsic microstructural property of gold; melting point is a dispositional property fixed by gold's structure plus external laws.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
Kripke's original necessity-of-identity arguments apply to constitutive essences, not to relational, law-dependent dispositional properties.
?
How convincing is this?
Think about whether this reason is strong or weak
3.
Conflating constitutive and nomic necessity illegitimately extends Kripkean essentialism beyond its intended and defensible scope.

1.
The melting point of gold is a nomic consequence of gold's essence.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
If the laws of nature are metaphysically necessary, all nomic consequences of a kind's essence are necessary properties of that kind.
