The best practices I'm talking about are built into the client software and a user doesn't need to know about them (new address per transaction already happens in most wallets). Again, totally not claiming linking ids isn't a problem, its just being touted as an impassable blockchain problem which is the basis of this discussion. The problem exists because governments are forcing all onramps to link IDS, not because of an inherent flaw of the system. Even with that 'flaw' other proposals/experiments already exist and work really well, and will probably be integrated directly into bitcoin in the future. An equifax-like service could exist that establishes credibility based on holdings or the public history of an address you control, not necessarily an identified individual. There are some clear benefits to that, one being your identifying information is not put at risk.
