The best protection against inflation, and meddling by society in general, is minimizing consumption in fiat by becoming as self sufficient as possible. This generally falls under op's category of acquiring productive assets but the end goal is not income generation or wealth preservation. Instead, it is freedom from both monetary and legislative oppression by eliminating unnecessary consumption.

This produces a more resilient and federated society and should be a major initiative for civil defense in a just world imo

Anyhow, good advice about preserving purchasing power during inflation in general, op. I appreciate it.
