As an aside, being a "Constitutionalist" like Varus is saying is a practice in insanity for several reasons.
1. First, it goes against the last couple hundred of years of legal matters. By saying the Constitution cannot change, it overrides every major SCotUS decision, because the SCotUS's duty is to interpret the Constitution - but judicial review like that is not mentioned in the document itself.
2. Constitutionalists fall into two camps. Ones who want the literal text, and ones who want the intent of the founders. Both are impossible.
A. Literal text: Times change, and the words don't. According to the second amendment, we can now possess WMDs, because those are "arms." We also have a freedom of speech that cannot be infringed. FIRE! FIRE IN THE THEATER! Totally allowed. Also, sometimes the literal text isn't clear, but there is no way to interpret it because interpretation is not being a Constitutionalist. Natural born citizen, for example, has no definition and thus is meaningless. It is literally impossible to follow the Constitution on that point. We need a president who is a natural born citizen, but we have no idea what that is. The best situation is to ignore it entirely, but, lolirony, then we aren't following the Constitution.
B. Intent: There is no way to prove or disprove the intent of the founders. There is no way for laws to be decided in this manner. We can "guess" intent... but let me know how well guessing goes for keeping a country together. One could believe the intent of "general welfare" encompasses social security, but another might disagree - and there's no way to decide it short of amendments. The SCotUS can't do it because judicial review wasn't directly placed in the Constitution. The document in effect becomes a Bible. There's no way to prove any of it, no interpretation can be proven "correct," so you just end up dividing people.
So in the end, there is no way to make a functional government work by being a strict Constitutionalist. Instead we have the Supreme Court to decide if something is true to the Constitution, and we use their decisions as the correct interpretation.
