The collective right never made any sense in the first place, not a single other amendment in the bill of rights is viewed as a "collective right" so why in the hell would this lone amendment be a "collective right"
Further what the hell does a "collective right" even look like in the first place....
the ACLU hates guns, does not believe anyone outside the government should have guns, the "collective right" was just their cover so they did not have to admit they only stood for some of the constitution not all of it
//EDIT: Mods have rate limited me, so in response to comment below allow me to add
I guess I should have implicitly stated Constitutional Rights, and more specifically Bill of Rights in the context.
On top of that, that is still not a "collective right", that is more of a Balance of rights, You have a right to your property, I have a right to my property, if your actions (aka polluting ) damage my property then you have directly harmed my individual rights and are thus liable
An example of this would be the fact that I have the right to swing my arms, but if I swing my arms in a manner that hits another person I have violated their bodily rights not to be injured by me. No one would claim that is a "collective right", no here we are balancing individual rights, their right to not be injured trumps my right to swing my arms in the physical space they occupy at that moment
