This is probably a non-starter in many cases. In my country, we had an e-health system that had millions invested in its development (we're a small country) and yet didn't work, nor was it really compatible with the systems already in place: https://www-delfi-lv.translate.goog/news/national/politics/e...

> Title: E-health is written off: those responsible for the "fraud" worth millions went unpunished, will create a new system
> Excerpt: Its unpredictable operation has caused quite a lot of worries not only for doctors, but also for patients, who may go to the pharmacy for the medicine prescribed by the doctor and not get it, because e-health has rebelled. Likewise, e-health tends to be incompatible with the local systems of some large medical institutions, so there are situations when the electronic referral of a family doctor to a medical institution must be printed anyway.
> On the other hand, doctor Nīcmane-Aišpure remembers a case when she visited a patient during a home visit, concluded that the condition was serious, wrote an electronic referral to call an ambulance, but "the ambulance is unhappy because the electronic referral cannot be opened".
> The eHealth system also still requires users to perform many manual steps. "It is a manual system, where at best you can extract some Excel files," says Solvita Olsen, a sworn lawyer and associate professor at the University of Latvia, who has been following the e-health saga since its inception.
And that was a system that didn't even try anything new, how do you imagine most mediocre countries out there will manage to deal with the technical complexity of blockchain based systems? Why even bother at that point, wouldn't they be better off with an XML or JSON schema or whatever other lowest common denominator one can come up with, to have some base data about the person and then additional bits that might be dependent on each country's laws?
It's not like there aren't people that enter the data in these systems anyways, in your example of shipment tracking, someone could enter whatever data they want regardless. Want to make it appear that a package has left the country, even when you haven't bothered to send it out? Sure, just bribe whoever is running the system, very much like: https://xkcd.com/538/
