Yes. In fact, you already do this most of the time. The right to be forgotten is so fundamental to humanity that humans have to expend extra effort to violate it and remember stuff. Machines with perfect memory violate the right to be forgotten by default and we have to tell them to forget things. Hence the regulation.

I don't do this most of the time. It keep a diary. I keep records of all kinds of stuff.

I would be uncomfortable if I had found out your diary contained as much about my daily travel and grocery errands as I know can be bought by marketing firms, or anyone with the right relationships in the industry. For that matter, the friendly greengrocer doesn't know what I bought at the shoe store.

Do you... write down the name of every person that walks into your store, then cross-correlate so you have nice little lists of every time each person came in and what they bought and how they looked that day? Because doing the same thing online companies get away with is generally seen as stalking in the real world.
