Bitcoin is effectively new ground so it makes sense that it does not adjust to the current models and if successful then the current models will have to be adjusted, this is one of the reasons why there is so much opposition to bitcoin by the way, think of bitcoin in the same way that electricity was thought at the beginning, it was a complete new industry and at the time it did not made a lot of sense to introduce this new technology when the technology of Kerosene lamps was so trusted, why people at the time needed electricity to light their streets when Kerosene was doing such a good job already?

And that is the same question that people ask themselves about fiat and bitcoin, why do we need bitcoin as a currency when we already have fiat and can use it to buy whatever we want? And the answer is simple because bitcoin is the superior technology and it is based as well on superior principles.
