I don't know why you are asking this question because the answer seems to be pretty straightforward. All transactions are set in stone on the blockchain, so to speak. There is no way they can be extracted and forgotten, but the right to be forgotten looks and sounds like a new buzzword in the Western world today. Blockchain clearly deprives everyone of this right, hence the need for anonymity. Long story short, you should stay anonymous if you don't want to be remembered forever.
