Actually it is out of necessity on some level. My landlord needs me to pay rent with dollars, because my landlord needs to repay a loan to the bank and the bank will only accept dollars. The bank only accepts dollars because if my landlord defaults on said loans the bank will go to court to resolve the matter, and the courts only deal in dollars. Similarly, we all must pay taxes of one form or another, and we must do so using something the government will accept, which is dollars and not Bitcoin. (You can adjust the currency for whatever country you might be considering if dollars are not the local currency.) Don't kid yourself -- without exchanges of some sort (including payment processors) cryptocurrency is basically worthless.
