I'm not recommending any other methods that will make it possible to obtain anonymity. Instead, I'm proposing other ways of protecting personal information that don't require arriving at an anonymized dataset.
In fact, the reasoning is wrong: It's impossible to anonymize data, since it can always be reidentified, which has been scientifically proven. The problem is that we cannot model what is already known about the individuals we are trying to protect. I gave the example of transportation data; people already had information on their colleagues and knew which times of the week they had taken the bus. That's what they were using to de‑anonymize the data.
