While that is better than nothing, for example US citizens are limited to only $10K USD in I-bond purchases per year per Taxpayer ID Number (TIN). Some people run their I-bond purchases through LLC's they control as well, but I don't know how the IRS would treat a fleet of LLC's set up purely just to get a TIN to use for buying I-bonds. Oil and copper tends to follow inflation, but they're highly volatile so you can't rotate into them expecting good liquidity. If you hold say $100K+ USD you want to rotate and re-deploy after the carnage with fairly liquid assets at relatively low risk, then I can't think of much beyond take the hit in a conservative cash and select bonds positioned in a capital preservation posture, or Benjamin Graham-style conservative value equities.
