well, we live in a fiat world. bitcoin can be as cool as it wants, but until economies make a base valuation in btc, this will never be the case. people that harvested raw goods would need to accept and be able to pay for equipment in btc; the companies that ship the raw materials would need to be able to buy vehicles and fuel in btc as well. the refinery would need to conduct business in btc; this would go all the way up the chain to the retailer selling the product, which would need to be purchased with bitcoin. and all the workers involved in the production of this product need to be paid in good old btc

so you pretty much see how this is impossible, and why you will always need to convert to your local fiat before you can really "spend" btc.

or you could just get a bitcoin debit card
