Aren't dollars and assets fundamentally different things? Land would keep up with inflation, while dollars wouldn't for example.
Also, many real assets are very dependent on real rates, for example real estate or gold. Imagine the mortgage rate tripling from today's levels (definitely possible), what do you think this will do to prices? I.e. what would happen if all mortgage payments increased 3x for new mortgages?
With gold the story is actually similar, because gold is like an very long duration ultra high quality bond.
If it happens yeah pretty likely getting real estate and preferably on mortgage will do splendidly.
