You also have to add the big limiting factor - the SSPX (and all independent chapels) are not parishes. No Trad Bishop/priest has jurisdictional authority over any layman. So, laymen aren't obligated to strict obedience, as in the past. Trad-land is the wild west. Priests can preach til they are blue in the face, but it's just a suggestion. In this regard, they have fulfilled their duty.

In pre-V2 times, bishops/priests had more authority, so their duty was also more elevated. Today, it's just a different story.
Agreed.
Also in trad-land you have one priest contradicting another.
And the advice is often really off the mark.
