Umm....
The LITERAL Babylon was destroyed many centuries ago. It was non-existent when Revelation was written. That is one reason why Babylon refers to anything other than literal Babylon. The question itself makes literal Babylon non-literal when is adds "confusion, or false religion." LITERAL Babylon would LITERALLY refer ONLY to the city of Babylon or the country of Babylon. The Revelation text even specifies "city."!!!
Revelation 18:9-10
And the kings of the earth, who committed acts of immorality and lived sensuously with her, will weep and lament over her when they see the smoke of her burning, standing at a distance because of the fear of her torment, saying, 'Woe, woe, the great city, Babylon, the strong city! For in one hour your judgment has come.'
The verse does not state, "the great confusion, Babylon, the strong confusion." The verse does not state, "...the great city, false religion, the strong false religion." To say the word "Babylon" is indicative of confusion is to make the word non-literal, to treat it figuratively as a symbol of metaphor for confusion (not to mention you've confused Babel with Babylon). Lastly, the literal Babylon and its figurative significance as a place false religion are not mutually exclusive conditions.
