Personal information covers many many data points, some intrinsic (your birthday or the enormous data set known as your dna) but many age out (income, spending patterns, content interests, residence location and travel patterns, things you own, assets, blood markers) and as abstract data sets can be thought of as seeing continual additions. Even intrinsic data sets can be thought of as aging out- new dna processing techniques producing more refined data points. The legal regime and the incentives/consequences around storage/use/misuse of both types of data is also not static, with US, China, and EU representing 3 distinct loci. There is an argument that the EU loci- which is good for ordinary humans- is in fact winning, since the regime most impacts global businesses and in picking a standard practice global businesses need to align with the most stringent regime in which they wish to do business.
So the situation in reality is dynamic and as an individual adopting practices that align with the rights to control your data that you should have is...more valuable than just virtue signaling.
One major area, for example, is around use of Plaid. Plaid builds credit-like financial models based on deposit data, which is wholly new in the financial world and egregiously privacy violating, in addition to being unregulated. Despite the convenience, think about not using it?
HTH. Cheers.
