Much of the inflation is caused by monetary policy (e.g. fiat money and expansion of the money supply).
The last time people cared about inflation in the 70s it was caused by an oil crisis; this time in housing inflation it's a lack of supply.
Austrians constantly predict there will be extra bad hyperinflation in the US from the national debt; not only are they wrong but they caused the 2008 recession by being wrong.
Luckily most people do want to make transactions in the official currency though; that's the upside of sales taxes.
