What to buy during inflationary periods

Yoda on inflation, courtesy of Wikipedia:

"The assets and commodities that would go up in value are those whose supply are finite or non-renewable (such as fossile fuel and real estate near areas of centers of trades). The assets and commodities whose supply are increasing would see its value to fall (including money).

How can the value of money to fall when there is no inflation?"

Buy oil you will, hmm?
