If the thesis of the thread was "Gee, it sure sucked to grow up in Argentina in the 70s with no access to high-quality financial products." that would be extremely relevant... but the thesis is much more expansive than that ("Prepare for a fantastic lesson about the power of inflation." / "Takeaway: may the sign of the exponential be ever in your favor. Positive, you own the world. Negative, you get diluted into nanoparticles.").

The folks getting spooked about inflation right now and reading this thread (it is written in English after all), almost certainly can invest even very small amounts in high quality investment products. There's no need to get fatalistic about saving ("you get diluted into nanoparticles."), it has never been easier for normal people to put their money to work productively.
