Going after data brokers seems like low hanging fruit, and necessary even if the ID system needs to be replaced. This is a top level issue that need to be addressed regardless.
While I think it’d be great to design a system where the information you mention is harmless (I’m curious how this would work without just shifting the problem to whatever new identifier is established), the reality is that this information is not harmless, and will continue to be dangerous to leak for the foreseeable future due to the myriad of systems that use this data in its current form. Any theoretical project to replace this would likely be a long and drawn out undertaking. Addressing the information environment in the meantime seems like a good idea.
