I find this notion that people are aquiring Bitcoins in the market to then spend at a normal retail establishment to be quite odd. Its daft to purchase something only to use it to purchase something else, where that interim step is unnecessary. I'm sure there some cases, some for the novelty or to see how it works, or edge case financial situations. But it doesn't make much sense to risk the loses in exchange or the transaction costs to do so regularly. I expect the vast majority of Bitcoin sales through regular retailers are from self-mined stockpiles.
I take your point but a number of us want Bitcoin to succeed for reasons other than speculative gain.
On principle alone I'll shop at a business that accepts Bitcoin, even if it costs me a little more. Amazon has lost a sale or two here of there because of my policy. And I tend to buy back a little more than I spend each time. I'm with counter on this one.
