Many Anglicans have indeed gone home to Rome. Many have the understanding that TEC is Catholic without the pope. So, yes, in the US, going back and forth between TEC and RCC has happened for centuries. When I was in Boston, it was difficult to distinguish RCC from TEC churches and services, other than the ordained women.
Yes, many self-identified orthodox Christians will continue to consider RCC and EO. After all, if the central issue uniting a Church is doctrinal purity (and finding a Church that agrees with me), then moving to RCC or EO makes sense.
I agree that orthodox Anglicanism is close to RCC (and EO for that matter). Many would disagree. Their option is the very evangelical ACNA.
===================
Perhaps, in the end, one question is the understanding of Church. If it is the Baptist/Protestant understanding of the universal, invisible church, the parish is the center, with little need for sacraments, hierarchy and unity. There were 14 organizations of Baptists when I was a member.
===================
I am one who is considering leaving this hodge-podge of churches, where schism is a natural and accepted consequence of differences of theological opinion. For me, that is not what Church is about. Perhaps, some day, I will give up on the idea of a universal Church and accept only a universal church.
====================
Many here point to the Protestant Reformation as a great success. IMHO, Luther would take his posting down from the wall if he saw the consequences of his standing for reforming the Church. IMHO, the idea that it is right to form a new Church whenever we have serious enough disagreements is at the heart of the problem of 21st century Christianity.
And yet these people don't seem to feel they ought to go join the RC Church, despite it being pretty darn close to orthodox Anglicanism - it certainly doesn't have any of the major Christological heresies that many say are the only real reason for schism.
It is a very strange combination of beliefs.
