In other words, my consciousness is not a unique thing universally speaking. It is only unique within the coordinates of spacetime where I exist. But the very basis of reconstitution of consciousness implies that it is universal and trumps spacetime (my grand father's consciousness should be reconstructed as should be mine equally at the same time). This creates a paradox that's impossible to overcome.
I think it is a problem insofar as you ascribe personal identity to individual particles. And although we don't shed and replace neurons the way we do skin cells (and the blood-brain-barrier exists) brains are not chemically stagnant: chemicals already exchange in and out of the brain; microglia already heal and repair neurons; and there are already parts of the brain where neurogenesis occurs.
In other words, although I agree with the problem you've described (that the same particles can be recycled in two different brains), it is also true that the brain is already not completely static and does recycle and exchange chemicals on its own. I think we simply don't know enough neuroscience to understand how a person maintains continuity of identity despite all the changes that occur naturally. And I'm sure there are people who would argue that we don't―that we are a different person every day.
There is not one single atom in you now, that was in you as a sperm or egg, or even a fetus or baby when you were born.
Life is literally a constant exchange of atoms. Your brain is like the rest of your body, constantly passing atoms around like an Olympic relay race, eventually having the atoms cycled out of your body. As long as the organ is in tact and healthy, it is a relay race like passing a baton in which each runner "atom" does not stay in the race(body) forever.
Biological life can be thought of like a living fractal. Constantly changing, never staying the same, new participants passing the baton in the race and leaving after a short time, but keeping the structure in tact, like a bridge, as long as new construction workers come in to replace them. But even with that constant turnover, that relay race, construction can't last forever. That is why all life dies, even if the atoms move on to other events.
