There are three echelons of commodity resource values:

The top floor is occupied by Mediums of Labour Exchange Currency of Assured Value
The second floor is occupied by extreme rarities like gems, art, antiques and (lesser) precious metals or Mediums of Savings
The bottom floor is occupied by all other (finite or not-so) commodity resources which are Mediums of Investment

The top floor occupants must struggle to retain their tokens value to save everyone from starving to death.
The second floor contains rare and finite things certainly assured to only ever inflate in value
The bottom floor contains stuff that may inflate or deflate in value, it's a circus of games we call an economy.

The seeming "price inflation" of "finite" Mediums of Savings ("hard" assets) are the direct and unavoidable arithmetic consequence of "infinite" (or at least much less finite) economic growth.

Nowadays individual commodity resource "price inflation/deflations" are minute and relatively insignificant components of all large economic pictures, save in the area of marginal profitability and comparative advantage analysis. There's nothing anyone can really do about them, they come and go, they have to exist.
