"partner" up with a few other businesses in your local area and use Bitcoin as your "local currency" and don't exchange it outside of it. It'd be an honor system, but after so many businesses accept it, it should still improve your corner of the world, financially, and therefore allow you more of an opportunity to work and make the bitcoin back from others you have paid with it.
The only thing making Bitcoin worth something is the BELIEF that it can always be traded or transacted to get whatever other thing you want.
I'd think if you started a local exchange, there'd be no competition so you could be selling them at a higher exchange rate and then invest further into Bitcoin by the profits being turned back into MORE Bitcoin reserves?
