Security requires good governance and trust - and ultimately realizing that everything connected online can and will likely be breached - and so if something is important enough, the design should be that it never touches the network. I personally don't fear any of my history or life coming out if it were - at least at this point, and in reality if security becomes a real concern due to well, tyranny and the universal battle against bad actors/evil, then my current location would be the only thing I'd ultimately not want known - and so you simply stay off grid then.
