Yes, I wish more people followed your advice... for anything, not just blockchain. If you don't want your personal information leaked, never post it anywhere, blockchain or not. Now, unfortunately, as you comment, this isn't necessarily always practical. So what do we do about that? Well, ugh! This is why buzzwords of "blockchain" like this article is trying to cash in on, are annoying. A blockchain does NOT have to be an immutable ledger, all a blockchain has to be is cryptographically signed/linked data. Sure, Bitcoin uses a blockchain that is computationally difficult to rewrite, and therefore for all practical purposes immutable, but it also isn't scalable for storing everybody's personal information. Instead, you can store people's personal information in a blockchain, and since they are the cryptographic holders of that key, they can null out their data if they want! This will actually make it easier to comply with the laws they reference, not harder, because people are self-sovereign over their own data and identity. In fact, we've already implemented a system like this, check it out at https://hackernoon.com/so-you-want-to-build-a-p2p-twitter-with-e2e-encryption-f90505b2ff8 https://hackernoon.com/so-you-want-to-build-a-p2p-twitter-wi... .
