Strictly from an academic exercise, what would you be willing to give up in order to get what you wanted in a new or modified constitution? For example, to abolish abortion as a “right” would you give up free speech on the internet? How about adding term limits on Congress and the SCOTUS. Would you or anyone else compromise away the 2nd amendment. I can’t guarantee that something won’t happen in the future that will turn a majority against the conservative reading of the 2nd or any other of the BoR.
Everything is a risk. Not having an Article V Convention could lead the federal government continuing to erode our rights. The federal government does that all the time and without the need for 38 ratifications.
