Wallets have 2FA, not coins.
Wallets are more like banks, except the user owns their own bank.
The issue with theft over the last year was primarily from rug pulls, bugs in contracts and things like phishing/domain takeover.
$3.8B in fraud from crypto out of the over 2 trillion worth of crypto transaction volume is nothing compared to the Zelle and FinCEN fraud with the trillions of illicit transactions allowed by the banks.
Social engineering attacks getting people to divulge their private single keys are a huge method of crypto theft.
That's a function of the wallet, we call it multisig.

Correct and 2FA would do nothing to stop that. The same problem exists with Zelle in traditional finance. To the point that banks are no longer accepting Zelle.
Interestingly enough, one of crypto's biggest critics, Elizabeth Warren, has also been after Wells Fargo for Zelle scams.
