I quite agree with you but not totally, wallets been traceable doesn't in any way give an edge to hackers, individual security mindedness or awareness is needed to keep our wallets safe from hackers, blockchain protect our identity from been revealed. There are many known whale wallets that house millions of crypto assets but still didn't get hacked.
We still needs the absolute privacy and anonymity for our transactions and I love what the privacy coins like veil project mentioned above are doing by offering us the opportunity to be 100% anonymous in our day to day transactions.
