Remember it's an amendment. Which means it can be repealed. We also at one point had an amendment outlawing all liquor and then another that repealed it. The inverse could be done easily with the 2nd.This is something that often goes without mentioning, so thanks for bringing it up.
The founders were not idiots. They did not want to create a set of stone tablets, a collection of unchangeable holy texts. The Bill of Rights and the Constitution were intended to be changeable, living documents, adaptable to the times.
Maybe it's time to question whether or not the status quo can scale and remains consistent with our societal values.
