"1a. is the primary concern for me, and while I can disassociate my identity from a digital address, that would defeat the purpose of using digital addresses"
Yeah but you would still have better option than not being able to do that I think this is just move the security debt elsewhere which is bad/good it depends on theirs ends
I don't agree with that - it spreads complexity all over without much of a benefit. You get the privacy downside of digital addresses having this "stalker" effect, and in turn everyone has to not only work to add support for these digital address codes, but they also need to make their systems robust to digital addresses being revoked, which they probably wouldn't.
In the status quo, it is clear you need to update addresses if you move; even if you don't, because you have to file a 転居届, Japan Post knows they need to redirect mail to your new address anyway; and you don't have the privacy worries.
well that why they can change,disable,multiple (?) address tho???
I can see something like this 1 address for work, 1 for house, 1 for vacation house etc
What I'm trying to say is that there are ways of achieving this without that privacy issue, since you're trusting Japan Post with your address anyway. See my other comment that I replied to this thread. It seems like the design itself is fundamentally flawed when a different approach could allow people to maintain their privacy while also achieving convenience. I say this as someone who actually lives in Japan, and after thinking about it for a few minutes, has come to the conclusion that this is probably not going to fly - Japanese people don't like the idea of a national ID at all, and are very sensitive to privacy concerns.
