"Average price data for select utility, automotive fuel, and food items are also available."

All of these are commodities. And every single product derived is based on commodity. Most commodities can be traded on commodity markets.

Yes, but all of them being commodities (what I said) is not the same as inflation only being accurate when someone purchases every commodity available in the marketplace (what you said).

Thats exactly how asset managers construct a portfolio thats suppose to track inflation.

Inflation of a portfolio of iPhones is completely different than inflation that an average American pays due to cost of living changes in the economy. You're cherrypicking a hypothetical scenario that doesn't apply at all to the example at hand, which is the average person's ability to pay for emergencies that arise related to living expenses.

All I am saying is that $400 in 2013 is not worth $430 today, Its wort a LOT MORE! Stop arguing like a idiot.

Which includes blackbox modifiers like "hedonic adjustments". So if it costs you $800 to get a cast for your broken leg today as opposed to $400 a few years ago, but they claim the quality of the cast is twice as good, then they say there was 0% inflation as you are getting the same "value" even though its costing you twice as much to fix the same problem.

According to that link you provided, hedonic adjustments don't apply to healthcare services.
