You don't have to be Roman Catholic to believe that; it's pretty much tautological. How can the schism end if nobody on the Orthodox side has the authority to end it? (And by "nobody," I'm not necessarily talking about a single individual.)
And proposing that Rome simply surrender is completely unrealistic, and also illogical. (Is the Pope going to infallibly define for the whole church that he has no authority to infallibly define anything, and no authority outside the See of Rome? If we simply adopt the Orthodox model of authority, nobody on our side has the authority to end the schism either! You can hardly expect the Pope to exercise Papal authority in declaring that no Papal authority exists.)
Supposedly, y'all do have a "command structure" that can make "binding decisions" ... an ecumenical council. However, any attempt (by whom?) to call such a council to discuss reunion would no doubt split the Orthodox, and any reunion settlement arrived at would no doubt split you further.
And we haven't yet considered whether such a settlement would cause a schism on the Catholic side of the aisle. (It likely would.)
Perhaps the first step is to agree that neither the absolutist Orthodox position (the local bishop is the fullness of the church, and nobody has authority over him) nor the absolutist Catholic position (the Pope exercises full and immediate jurisdiction over the whole church, and has authority over every bishop everywhere) are tenable models for a post-schism church.
It's a mess. At least we're talking about the mess, but still: Come, Lord Jesus.
