This is an easy caveat to make as there are many other parts depending on how the US government calculates inflation.

And there aren’t alternate inflation calculations out there, and certainly no consumer financial instruments pegged to them.

For all its flaws, it’s the best we have. I think it’s not discussed because it’s such a sunk risk that it’s not really anything that would change someone’s mind.
