Not that it matters, but I Disagree with the court's argument.
A Trust is often considered a distinct legal entity which is why so many people use a trust to purchase NFA items. My trust owns my NFA items, not me. When I die, my possessions, including all of my guns and accessories, will stay owned by the trust so my wife and kids can use them without having to do any transfer. A trust is as much a legal entity as a corporation, which does have "rights" according to SCOTUS.
The Second Amendment does not create rights, it affirms the rights. Since the Founding Fathers were so against a standing army, they wrote the 2nd A. so that the people could be the military in times of need. A military needs access to all of the modern equipment, not just self-defense focused arms.
The right to self-defense exists regardless of, and outside of, government regulations. It is a natural right that all living organisms have. The Founding Fathers knew that, therefore they didn't need to write a sentence in the new Constitution to protect it. In other words, even if the government is dissolved, the right still exists.
