Is a seperate amendment based sufficiency argument necessary?

I noticed yesterday that even in my task of trying to make my case from the second amendment itself, it is not necessary to make a separate sufficiency argument from the amendment. Instead, my other argument that the "necessary to the security of a free state" did not come from the authority of writing a constitution as is the case with the do and don't parts of the constitution and was not intended to be taken as always true regardless of reality  would by itself allow considering the sufficiency part if it is understood to be a part of being "necessary".
