It is for federal due process purposes. States have their own Constitutional clauses regarding equal protection.
That is the point.
Protection of individual rights from state abuse was not originally a federal responsibility.
It only became a federal responsibility after the Civil war, the 14th amendment, and blatant discrimination by the states.
But after the 14th amendment, the courts were forced to look at the 2nd amendment in a new light.
They found that the motivation for the 2nd amendment was mostly from individual defense rights.
Which then made some local and state gun control laws illegal.
Hence Heller and McDonald.
Which is not far enough.
Almost all gun control laws likely are illegal.
