Your essay makes a very thought-provoking and philosophical read. You question many assumptions as category errors, and you may be right. Your conclusion is Philosophical presentism, only the present is real.
I think this is certainly a defensible position. Why do we need to think of the past as real when all we know about it are our memories and deductions in the "fossil" record that exist in our present knowledge of information, and as for the future, it has not happened yet? All we know of what is to come is uncertain predictions that we can make with our present information. If our experience is everything then it is formed from only the information that we possess now.
If we accept this presentism then what should we say about places that are far away? Do they also not matter because it is only the information we have now that matters to our experience? Information transfer is limited by the speed of light so if time is stationary then we have no real access to places beyond our own mind.
