"being" is about being- 3 : A "because" Equivalent

A "because" equivalent to the second amendment from the side representing the significance of using "being" in time and reasoning would modify the substitution cited by the Supreme Court in District of Columbia v. Heller as this:

"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"

District of Columbia v. Heller

to something like this:

Based on what currently exist a well regulated Militia is necessary to the security of a free State and 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.

  

"being" is about being- 2: An Essential Distinction

I think that one thing that could impede understanding the potential significance of current time dependence or reference in "being" as used in the second amendment comes from not sufficiently distinguishing between two different things and confusing them as one. These two different things are:

1- The expression made in the second amendment in relation to the necessity of the militia:

I have no argument against the claim that expression was intended to apply on all time and the "being" argument I have been trying to make has nothing to do with that.

2- The expression made in the second amendment in relation to the EVALUATION for the necessity of the militia:

Here is the place of this "being" argument. The "being" ,as used in the second amendment, significantly suggests intentionally showing that although the expression related to the necessity of the militia could have been intended to apply on all time, the evaluation because of which that was made was intended to apply on that time.  [(Added 2/2/2014) one may express that last part better in this way: The "being" ,as used in the second amendment, significantly suggests intentionally declaring that, although the expression related to the necessity of the militia could have been intended to apply on all time, the evaluation FOR which that was made was made to what existed at that time.] [(Added 2/4/2014) that may be expressed better as:
The "being" ,as used in the second amendment, significantly suggests intentionally declaring that, although the expression related to the necessity of the militia could have been intended to apply on all time, the evaluation  because of which that was made was made FOR what existed at that time.] 

"being" is about being

I do not understand how "being" in the second amendment was understood to refer to an always existing status. "being" is about being.So it always refer directly to the current status. It is only when that status wont change with time that reference would indirectly expand to all time. The significance in that those who made the amendment were pointing directly to only the current status should not be ignored. They could have chosen words like "because" to make an all time direct reference instead of pinpointing directly to only their current time. 

It is not far from normal when people limit themselves to what is needed for their time and understand "being" to mean "because" but that changed to become no longer applicable a long time ago.
