They're confused, it's deflation that is the issue with Bitcoin - not inflation. Since there never will be more than 21 million Bitcoins in circulation due to how the protocol is coded - as Bitcoin becomes more popular everything will become less expensive (requiring less Bitcoins to buy, making Bitcoins more expensive). While early adopters could easily buy thousands of Bitcoins for "nothing", a single Bitcoin today costs $46.
