The Constitution is on it's way to becoming a dead letter. There's nothing wrong with rebooting the Republic, many countries go through such disruptions. I'm not saying just do it, but if the existing political consensus collapses we won't benefit from trying to back to how things used to be.
One of the very first changes of any new version of the Constitution arising from any major quarter would be the deletion of the First Amendment, with the Fourth following closely. I have no faith that a document reflecting contemporary American generational consensus, as Jefferson aspired to, would be better or more free.
Could =/= would. If you're arguing for the status quo because every alternative you can imagine is worse then you're essentially treating it as religious dogma.
