Unfortunately, if you want to do anything meaningful in this world, it requires providing documentation. Your fear is justified, but also, in my opinion, a bit exaggerated. I'd be more concerned about stacking as much #Bitcoin as I can, before the rest of the world wakes up. The wealthiest people out there have to provide KYC info, to do their thing. Not to be offensive, but I doubt that your data is more valuable than theirs. Just my 2 sats...
The wealthy have the time and money to take care of things if their data is stolen. Best I can do is keep my info safe, because I have neither the time and money. Time running out is what worries me and frustrates me about this issue.
