The funny thing about that thread is that the best answer is "by not holding cash."
Inflation hurts cash. Conversely anything denominated in cash is "helped" (nominally) - debt, equities, etc. If you, like parent comment, have "most of my money is in index funds and FAANG companies" then you have benefited from inflation (NASDAQ is up 35% from a year ago). On the other hand, people who are hurt the most by inflation are low net-worth savers and wage earners.
It might be counterintuitive at first but while you are exposed to a potential crash by holding equities, by holding cash you are guaranteed to lose purchasing power equal to the current rate of inflation (and it's worse than the official CPI makes it seem).
For your cash positions, which should be kept as small as possible (examples being upcoming purchases, dry powder for investing ideas, emergency fund, etc), liquid US dollar alternatives exist that you can consider diversifying into. These include other currencies, some crypto, precious metals, etc.
You had to wait until 2013 to have what you had in 2001, which is awful. Better than cash for 13 years yes haha but a diverse portfolio with other things like gold which went nuts over that time would be way ahead.
