The precious thing about bitcoin is that even if you hold a billion dollars worth of Bitcoin, no one will know crap about it since Bitcoin is highly private and untraceable unless the holder exposed his ownership of the wallet holding the Bitcoin.
You are correct that privacy feature of Bitcoin is important for those individuals who never want to disclose their identity, but as we are all aware of the fact that all transactions are recorded in cryptographic addresses rather than with real names on public ledger (bloc chain), which is visible to any person. I think by employing certain techniques, it is possible to analyze block chain and potentially trace the flow of funds, and reach the individuals or entities involved in transactions.
Why think about it? We already know that any transaction will be recorded by Blockhcain and whoever finds our transaction they know it as long as we are not too vulgar to have bitcoin and enough privacy is yourself who knows not about other transactions.
I don't need any particular technique for your Bitcoin holders just store it in a hardware wallet and it's safe and no one will reach it individually, no need to worry about tracking the flow of funds because we haven't committed a crime so what is there to be afraid of?
