Why do you think "the beast" is a man? There is no mention of a man in the description - Revelation 13 (WEB):
(1) Then I stood on the sand of the sea. I saw a beast coming up out of the sea, having ten horns and seven heads. On his horns were ten crowns, and on his heads, blasphemous names.
(2) The beast which I saw was like a leopard, and his feet were like those of a bear, and his mouth like the mouth of a lion. The dragon gave him his power, his throne, and great authority.
I don't know of any men who look like a leopard that has seven heads, ten horns, feet like a bear, and just one mouth that's like a lion's mouth.
You might think it is not symbolic of a "non tangible thing like govt", but chapter 17 also talks of a seven headed ten horned beast, and the angel explains that the seven heads and the ten heads are symbolic of kings and kingdoms (governments) - Revelation 17 (WEB):
(1) One of the seven angels who had the seven bowls came and spoke with me, saying, “Come here. I will show you the judgment of the great prostitute who sits on many waters,
(2) with whom the kings of the earth committed sexual immorality; and those who dwell in the earth were made drunken with the wine of her sexual immorality.”
(3) He carried me away in the Spirit into a wilderness. I saw a woman sitting on a scarlet-colored beast, full of blasphemous names, having seven heads and ten horns.
(4) The woman was dressed in purple and scarlet, and decked with gold and precious stones and pearls, having in her hand a golden cup full of abominations and the impurities of the sexual immorality of the earth.
(5) And on her forehead a name was written, “MYSTERY, BABYLON THE GREAT, THE MOTHER OF THE PROSTITUTES AND OF THE ABOMINATIONS OF THE EARTH.”
(6) I saw the woman drunken with the blood of the saints, and with the blood of the martyrs of Jesus. When I saw her, I wondered with great amazement.
(7) The angel said to me, “Why do you wonder? I will tell you the mystery of the woman, and of the beast that carries her, which has the seven heads and the ten horns.
(8) The beast that you saw was, and is not; and is about to come up out of the abyss and to go into destruction. Those who dwell on the earth and whose names have not been written in the book of life from the foundation of the world will marvel when they see that the beast was, and is not, and shall be present.
(9) Here is the mind that has wisdom. The seven heads are seven mountains on which the woman sits.
(10) They are seven kings. Five have fallen, the one is, the other has not yet come. When he comes, he must continue a little while.
(11) The beast that was, and is not, is himself also an eighth, and is of the seven; and he goes to destruction.
(12) The ten horns that you saw are ten kings who have received no kingdom as yet, but they receive authority as kings, with the beast, for one hour.
(13) These have one mind, and they give their power and authority to the beast.
(14) These will war against the Lamb, and the Lamb will overcome them, for he is Lord of lords, and King of kings, and those who are with him are called chosen and faithful.”
(15) He said to me, “The waters which you saw, where the prostitute sits, are peoples, multitudes, nations, and languages.
(16) The ten horns which you saw, and the beast, these will hate the prostitute, will make her desolate, will strip her naked, will eat her flesh, and will burn her utterly with fire.
(17) For God has put in their hearts to do what he has in mind, to be of one mind, and to give their kingdom to the beast, until the words of God should be accomplished.
(18) The woman whom you saw is the great city, which reigns over the kings of the earth.”
So the book, which you think is clear and unambiguous, says that the woman who sits on many waters also sits on the beast and on seven mountains (she must have a large backside). She holds a gold cup that is somehow full of "abominations and the impurities of the sexual immorality of the earth" and she drinks the blood of Christians. The waters are actually people, nations and languages. The seven mountains that the woman sits on are in fact seven men who are kings, five of which are dead, one is currently alive, and the other is to come in the future. The ten horns are also kings of the future who will go to war against Jesus. Oh, and the woman is not actually a woman - she is a city, a city that reigns over kings! And the beast, which is 17 kings, is also a king, one of the seven kings. That is so clear, and obviously the beast is a man!
