Federal courts in the decade since have found many restrictions on the right to own and use weapons perfectly congruent with that decision. Heller merely says the government can’t enforce laws that prevent (most) Americans from possessing commonly used weapons in their homes for self-defense.

From the introductory paragraph in your own link. Again this isn’t whether most Americans can posses weapons but does a domestic abuse restraining order rise to the level of due process. Which oddly falls in line with the second paragraph of the source you linked:

Courts have found that Heller does not preclude laws that prohibit anyone younger than 21 from buying guns in retail stores; laws that bar people who committed a single nonviolent felony from ever owning a gun; laws that severely restrict the ability to carry a gun outside the home; laws that ban commonly owned magazines of a certain capacity; or laws that require handguns to incorporate untested, expensive, and unreliable “microstamping” technology.

There’s nothing I found in the article you linked which claims that the 2nd amendment is an absolute right that cannot be revoked. You’re arguing something that simply isn’t a thing and avoiding the actual question at hand.
