Agree with the property/lease idea. The basic tenet is that people must have full control over their personal information, and the infrastructure to make that happen must be a fully integrated service the government offers its citizens.
That means mutual authorization/authentication/et cetera, keep a log of who wanted to know what, provide for some sort of ``document pouch'' that can contain all sorts of different ``folders'' for different purposes (credit history, criminal records, medical records, any other purpose you could think up) with consent based access and, in certain cases overriding-concern keys so that, eg. emergency medical personel have access to the medical details.
Everything encrypted and all that too, of course. Such a system must also provide for artist aliases except perhaps for persons that have abused them previously. When the government stops trying to control the populace by sticking everybody in neat boxes of their bizarre and disconnected designs and instead starts thinking in terms of facilitating infrastructure for its citizens that only cares about the things that actually matter to its people, empowering things can happen.
It also means very careful consideration and then reduction to the bare minimum of who needs to know what, when. To help that along and amaze even further how little information you really need as long as it is the right bit of information, consider "zero knowledge proofs". Using that I could, say, prove I'm old enough to do something that requires a certain age (like, oh, buy alcohol or learn how to drive) without divulging as much as the year of my birth, nevermind name and all the rest as is the case now.
The math and the technology to do all that we already have. Visionaries in the right places to give us these wonders we have not and we are not likely to ever get with the current governmental system, nevermind the current incumbent party and their attitudes and issues. Carry on government.
