I don't have to. The fact is, no one prices their goods in BTC. Its absolutely ludicrous to price goods in BTC in the current market.

I think BTC has utility as a currency for exchange however. But on that side, you don't want to be in the position of hoarding BTC. You hoard dollars, and then use BTC to transfer dollars between people. Services like Bitpay allow you to keep most of your money in hard cash.
