When passing a Constitutional Amendment it's a simple solution because the details of doing it don't count.
Of course, I never asserted that the details don't count, but for some reason you seem compelled to argue against this position. Which you
can do, but don't expect me to continue debating the position that the voices in your head hold.
Again, a simple solution can be easy or it can be difficult. I'll give you another example. It's called the "Graph Coloring Problem" and it's computer science related, but I hope you can try to follow: given a graph G, our task is to return the k-coloring for the graph, such that no two adjacent vertices have the same color and there does not exist a k-coloring for a smaller value of k.
The "
simple" solution is to start with k=1 and attempt to find a 1-coloring for the graph. If no such coloring is possible, go to k=2, then k=3 and so on. For every k greater than 1, you simply have to generate all the possible colorings for the graph using pretty basic combinatorics, and see if they satisfy the "adjacent vertices must have different colors" restriction; the first one you hit is the solution. Despite being simple in principle, this solution is actually not
easy. Indeed, this problem most likely doesn't have an
easy solution at all (it's what computer scientists call an NP-complete problem) and if an
easy solution were ever found, it would represent a revolution in the fields of computer science, computability and mathematics, and a whole class of problems that are now essentially intractable would be trivial to solve by simply transforming them into a graph coloring problem through a reduction.
Back to the issue at hand:
The problem we have is how to (a) prevent Congress from passing more mandates and (b) prevent the Court from using the same reasoning to find those mandates constitutional.
The simple solution is to pass an Amendment to the Constitution (indeed, it's the
ONLY solution, but that's another topic of discussion) because such an Amendment would prevent Congress from exercising the tax power to pass laws that contain mandates and prevent the Court from finding some laws to be constitutional by legal finesse. But that
does not mean that writing and/or passing the Amendment would be easy.
But fixing a computer is a "complicated" solution because then, magically, the details do count.
You asked for a solution that's
complicated. I gave you one, and you complain about it?
Yep, you're right up there at the top of the intellect tree. 
Whether I am or not is irrelevant.
