I have to disagree with the author. If you aren't paranoid about security/privacy (which converge in this matter) you aren't doing due diligence. Addresses being a case in point. I like the "linkage, not address" is private data POV, I think that's a wonderful insight.
The problem is any information, used creatively, isn't something you want the bad guys to have. That includes the simple fact you exist. Our society's current security mindset is based on the antiquated notion of how difficult information about a person is to acquire. In the 19th century this was a perfectly valid approach. Information was siloed and guarded. Compiling information from public sources was literally too difficult to be practical, especially on a large scale.
Now, of course, not so much. But everyone is still acting like it's the 19th century. Governments, businesses, private citizens...
Add to the fact that information aggregation is a multi-billion dollar business (*cough* Google *cough*), businesses don't care to spend money on security (*cough Facebook *cough*) and you have our current problem and ham-handed government backlash like GDPR and its brethren.
Here's a thought. Make it illegal to store PII. I'm not talking about over the top things like names, but why does every business want my credit card number? Sure, it's convenient to not have to type it in every time but is that convenience worth the potential of being bankrupted? Or having my credit score (and that's another topic you shouldn't get me started on) ruined?
After all, what you don't know you can never give away!
To those who answer businesses need that info for analysis I answer BS! I do not exist to offer any business competitive advantage. I do not exist to allow others to profit from information that they scavenge from my giving them money for goods they possess.
While a magazine may need my address to deliver said magazine to my home why does Facebook need it? Further, why does Amazon need it? Surely I can give it to them for each delivery? They don't need it in between deliveries. I don't want advertising from them. I don't want constant harassment, tons of paper that ends up in the landfill. If I want to know about their special offers I'll go to their website and look!
Can you tell I haven't had my caffeine yet? (laughing)
