Most of the governments you are talking about are voted on by the people. And when the people care, the governments change. When the people don't care, yes, the government does want lots of data. However, people do often care about such things and that limits the government.
Voted on by the people, and yet in 2026 we have no way to actually confirm our votes are counted or factored into who gets elected. Every single US president is related, sans Van Buren, but there's no way our elections are rigged! Not sure how many corrupt politicians have to take office before people will start questioning the legitimacy of elections.

When half of American lives paycheck to paycheck they care about putting food in table instead of petty politics or data collections.
