Though I don't agree with everything that you've said, I am happy you took the time to engage with my content so deeply.
I have high regard for the technological ability of the US government, though I don't think they use that technological ability efficiently; I think that they could find a way to make the code of addresses anonymous in some way, though I am not an expert on that.
I am not entirely sure that I believe direct democracy is inherently a fallacy, though you raise an interesting point that people maybe should not vote on that which they lack technical expertise. My solution for that would revolve around increased transparency from experts that are handling something like military spending as there is currently a lot of waste undoubtedly when spending so much.
I like the analogy you have created where your neighbor takes on a different "country" because I believe that the divisions caused by nationality are entirely unnecessary to the functioning of the world. Rather than choosing the country you want to be part of, I would love a world where there are no countries, there are individuals supported by those in their community (not entire nation).
The banknotes comment was used to illustrate the diminishing buying power of the US dollar, an attempt at showing the severity of inflation. You may be more correct in saying we should be looking at monthly income spending power, but my assumption is that the trend of inflation will remain the same.
I'm not entirely sure about your last statement, but perhaps you could further explain it in a bit!
Once again, I'm not an expert and I am simply theorizing here as I find the intellectual exercise to be really interesting. Thank you for taking so much time to interact!
