I don't see the connection between having high price goods and consumables with bitcoin's price. Bitcoin is a deflationary asset and the more the price of these goods is being ticked in by inflation then that means that bitcoin's going to be higher than theirs.
Regardless of the situation of an individual, whatever the price will be for bitcoin, they'll allocate funds to it to buy or trade it as much as they want. Then the obvious is for those that have no capital, there's really no way for them to buy anything.
