You are operating under the delusion that our rulers and their oligarchy respect the Constitution and the Rule of Law.
Since they have rendered the Constitution null and void, how can you possibly think that tyrants are suddenly going to abide by any new additions to it?
Who is going to enforce any new restrictions upon tyrants?? How many divisions do we have to force them to comply with new Amendments when they no longer comply with the existing ones???
I have responded on this thread to argument 1) to the effect that process amendments are different from the kinds of evasions we are currently experiencing.
As to 2), a forcible takeover of the government is beyond the scope of this discussion. I do not believe a successful Article V experience would precipitate such a coup, or, put another way, men who would act that way because of Article V simply do not need the excuse.
