Disagree. Not how it is understood.
How so?
You can’t leave Daniel 8 out of this. The beast that appears last is plainly the same one in Revelation 13. If it was prophesied that early, and the prior beasts were identified specifically in scripture, looking back in history it is not hard to determine when this beast first arose—and the mark of an extant Beast was therefore revealed to John (if not known already).
