It is not divisibility that makes bitcoin unsuitable as a spending currency, it is the fact that its price keeps rising. Imagine if you are presented with two coins one that historically inflates and another that deflates and are asked to spend one and hold the other. Which do you pick? An inflating coin will always replace a deflating one as a medium of exchange. This is called Gresham's law. A coin with a fixed supply will never be suitable for daily transaction because the demand for currency isn't fixed (due to economic and population growth).
