Clause and Effect well done, but reaches wrong conclusion

from a NY Times article, Clause and Effect, by Adam Freedman

Likewise, when the justices finish diagramming the Second Amendment, they should end up with something that expresses a causal link, like: “Because a well regulated militia is necessary to the security of a free state, the right of the people to keep and bear Arms shall not be infringed.” In other words, the amendment is really about protecting militias, notwithstanding the originalist arguments to the contrary.

Not only originalists, Mr. Freedman, hold the contrary view. The Unabridged Second Amendment reaches a somewhat different conclusion.

[Schulman:] "(3) Is the right of the people to keep and bear arms conditioned upon whether or not a well regulated militia, is, in fact necessary to the security of a free State, and if that condition is not existing, is the statement 'the right of the people to keep and bear Arms, shall not be infringed' null and void?"

[Copperud:] "(3) No such condition is expressed or implied. The right to keep and bear arms is not said by the amendment to depend on the existence of a militia. No condition is stated or implied as to the relation of the right to keep and bear arms and to the necessity of a well-regulated militia as a requisite to the security of a free state. The right to keep and bear arms is deemed unconditional by the entire sentence.
