"Are we just supposed to passively wait another 70 years?"
Bingo! You betcha. Everything else has been tried.
...Yes, even Bp. Roy's idea. Several groups got together (as best they could -- Trads could never get along) and attempted to elect a Pope to bring an end to the Crisis in the Church. We have had several Trad anti-Popes over the past 56 years. The young will have to Google or ask on CathInfo for the names, since it was all before their time. But it doesn't change the fact that we've been there, done that, got the T-shirt.
Oh, but they didn't have a website.

Hey, patiently waiting and trusting in God to untangle a supernatural mystery puzzle is not exactly crazy talk. The various groups being invited to this meeting -- not a single one of them can give you an explanation of what happened with the Crisis in the Church, the exact status of the Pope, or how the Crisis will be fixed
with anything approaching certainty, authority, or perfection.
Oh, there are PLENTY of opinions, mostly strong ones. But every last position has an achilles heel or two, that people accept because it's the "least bad option" to them. But none of the options are perfect. If you don't understand (or accept) that, then your understanding of the Crisis in the Church is imperfect at best.
Is it logical to believe that man could solve a problem he didn't cause? Was the Crisis in the Church/Modernism a human screw-up that man by his own powers could rectify? I don't think so. Is the Church a human institution? No.
God struck the Church with this Chastisement, and we have no other choice but to patiently await His mercy in ending the punishment.
He was merciful in leaving us all lifeboats, so EVERY MAN OF GOOD WILL could reasonably find one if they wanted to. He is Merciful as well as Just.
But this Crisis is a chastisement, there is no doubt about that. Like World War 1 or 2 in the spiritual order.
