So we shouldn't be teaching newbies about best security practices because they are difficult? Just let them use insecure methods because they're easier? I don't think so.

Downloading and using a single authenticator app is hardly challenging. I stand by my original point: Of the commonly offered 2FA methods - SMS, email, app, hardware keys - SMS is by far the least secure. Just as we shouldn't be encouraging anyone to leave their coins on an exchange because it's "easier", we shouldn't be encouraging anyone to use SMS 2FA, and those who are should be encouraged to upgrade to an authenticator app.
