You may not wish to share it, but it's a simple choice:if those countries want that data, you'll either share it or be refused entry. Passports are only a small part of that, regardless of what data is stored on them. The US for example requires you to provide fingerprints and submit to a face scan, that then get permananetly stored (for non-citizens). They also require you to submit to a phone and laptop search if the TSA agent believes it's necessary. You are of course free to refuse all of this, and go back to the country you were coming from.

So having digital vs physical passports opens no new avenues of private data sharing with regimes you might not trust: they already have a right to demand any kind of data they want about you.
