No doubt you are wrong. Tell me how Jerusalem ever reigned over the kings of the earth (Revelation 17:18). Tell me how Jerusalem was "a prison for every foul spirit, and a cage for every unclean and hated bird!" (Revelation 18:2). Tell me how "all the nations have drunk of the wine of the wrath of her fornication, the kings of the earth have committed fornication with her" (Revelation 18:3). The waters upon which the harlot Babylon sites represent "peoples, multitudes, nations, and tongues" (Rev 17:1,15). How does that apply to Jerusalem?
Why can't that mean the old Jerusaem then? But not in a literal sense. And certainly not involving literal Jerusalem in the first century. In order for the NJ to make sense in the future, the old Jerusalem has to be found no more at all.
Revelation 18:12 The merchandise of gold, and silver, and precious stones, and of pearls, and fine linen, and purple, and silk, and scarlet, and all thyine wood, and all manner vessels of ivory, and all manner vessels of most precious wood, and of brass, and iron, and marble,
You have read Ezekiel 16 before, right?
Ezekiel 16:1 Again the word of the LORD came unto me, saying,
2 Son of man, cause Jerusalem to know her abominations,
Ezekiel 16:13 Thus wast thou decked with gold and silver; and thy raiment was of fine linen, and silk, and broidered work; thou didst eat fine flour, and honey, and oil: and thou wast exceeding beautiful, and thou didst prosper into a kingdom.
