This will only be the case if people actively work for bitcoin and pay with bitcoin, so there is no need to enter the banking system at all. We need to close the circle and stay 100% within bitcoin for true freedom to happen. Also, we must guarantee that people can keep running their nodes on their basements, if we depend on corporations to run nodes then we are screwed (big blocks problem)
The main question here is, can most people afford to run nodes in their basements if the previous incentive for doing so (mining rewards) has been removed? I shall add the tax thing to my reasons that newcomers should consider earning bitcoin and spending bitcoin instead of futzing around with exchanges. Let someone else worry about cashing in and cashing out; you just focus on using bitcoin to make the purchases that you would have made anyway.
