No, that's not the question at all. You are lumping together all forms of nuclear waste, and applying the long-term storage requirement of the least dangerous waste to the dangerous waste that is only radioactive for a few decades. Pretending that there is even a need to securely store material for millennia when equally radioactive products are found everywhere in the Earth's crust is disingenuous. Below a certain level it isn't any more dangerous than loads of other chemicals we have lying around that nobody cares about.
