Two equally large problems -- neither of which have anything to do with
encryption in transport -- are backend security and password strength.
In the former case, we've seen an ongoing parade of security breaches
and subsequent dataloss incidents.  That parade is still going on.
In the latter case, despite years of screaming from the rooftops, despite
myriad enforcement attempts in code, despite another parade of incidents,
despite everything, we still have people using "password" as a password.

As a side note, I've found it nearly impossible to get users to
understand that there is a qualitative and quantitative difference
between "password used for brokerage account" and "password used for
little league baseball mailing list".

The minor problem of passwords-over-the-wire pales into insignificance
compared to these (and others -- but that's a long list).

Um, those are exactly the consequences of passwords over the wire. If you didn't send "password" over the wire, nobody could guess that's your password on your banking site. "password" to unlock your local credential store of private keys is far less serious because they have to have access to the device that hosts those credentials. "password" to your bank, on the other hand, is just a https away.

the other thing this allows is people to have a single extremely good password that doesn't change to protect the local credential store, and also protects you from the idiotic corpro security theater which requires passwords to be changed so often that you have to write them down. on my own local machine, i get to dictate the policy not some corpro security thespian.
