No because whether he owns a bitcoin at $30 or at $30k a bitcoin is a bitcoin and at this point every wallet is indexed, tracked and any wallet with significant value (regardless of cost basis) is being mined for potential vulnerabilities.
The point being made is that once a wallet is connected to a real identity (as opposed to just knowing that wallet X has Y amount of BTC), the attack surface for that wallet is increased by magnitudes and entire vectors of attack are opened up (e.g. phishing).
