So, can you tell me how this services are going to pay their expenses?
I'm guessing the electric company and ISP doesn't accept BTC
Don't know if I understand your question/concern.
There is no problem if you convert bitcoin through an exchanger that is registered as an MSB (i.e. bitinstant)
Alternatively, miners can still sell all the bitcoin they want directly to people even if they don't go through a registered exchange. Just requires registration as an MSB which is not such a big of a deal as people make it out to be.
