You're making symbolic and abstract things that are not symbolic or abstract, and confusing kingdoms with people. Both kingdoms and kings are described as beasts in the Revelation and the book of Daniel, but confusing what is referring to actual people with what is referring to kingdoms or governments is a mistake. Knowing what refers to what, and what is literal and what is symbolic requires God-given understanding about what we read.
Just to set the record straight:
The antichrist (aka the first beast) is a person, a man, and not a system. He will be a Jew, and will fulfill---for those Jews who are not of God's elect and do not receive Jesus Christ as their Savior---the Messianic prophecies, and will be received and worshiped by them as their king and their god. He will be the head of the one world government, which is also described as a beast.
The false prophet (aka the second beast) is also a man, and will likely either be a pope or a priestly religious figure in the new religion of the antichrist---whatever offices and titles that religion may have.
And while the seal of God is spiritual---a metaphor for being sealed with the Holy Spirit (that is, born again/saved)---the mark of the beast will be an actual mark on people's hands or foreheads. The Greek word "charagma", translated as "mark" means a stamp, imprint or engraving---like a brand, or possibly a tattoo. It won't be a microchip, or an action of some kind ("doing this or that is taking the mark of the beast"), but an actual mark, voluntarily received by those who wish to buy and sell under the government of the antichrist, and not forced upon people (at least not Christians)---the consequences of not taking it notwithstanding.
(And the image of the beast will be an actual image that people will be worshiping, like a statue---probably in the likeness of the antichrist---just like King Nebuchadnezzar set up a golden image for people to worship.)
Rev 13:
The beast rises up out of the sea as the sea here is symbolic of people and nations as in a sea of humanity, Daniel Chapter 7:1-8; Revelation 17:15. This beast is the Jesuit Luciferians with their headquarters in the Church of Gesu in Rome.
Rome had total control from 538 AD to 1798 which equals 1260 years that equal time, times and a half time as once again history will repeat itself in the annihilation of Gods anointed during the end of days.
The seven heads are that of the Babylonian Empire, Medo/Persian Empire, Grecian Empire and Roman Empire. The ten horns represent the nations the Roman Empire scattered to when the deadly wound was put upon them, Daniel 7:23-25. The deadly wound came in 1798 when General Berthier of France captured Pope Pius VI, who soon died in captivity in Valence, on August 29, 1799. Seven of these nations are the ancestors of the modern nations of Europe.
These ten nations were the Anglo-Saxons (English), the Franks (French), Suevi (Portuguese), Visigoths (Spanish), Burgundians (Swiss), Alemanni (Germans), Lombards (Italians), Ostrogoths, Heruli, and the Vandals in northern Africa. The last three being Ostrogoths, Heruli, and the Vandals had already been destroyed by the Roman Empire before their deadly wound came in 1798.
What was and was not and yet to come has always been the Roman Empire that has always persecuted Gods chosen from the foundation of the world whose name is found written in the Lambs book of life. The beast out of the sea is the revived Roman Empire as its deadly wound is now healed as we see in John’s vision as Satan gives this beast his power, seat and great authority.
The beast was given a mouth speaking great things and blasphemies and power was given unto him to continue for three and a half years which equals 1260 days, Daniel 7:25; 12:7; Revelation 11:2, 3. And it was given unto him to make war with the saints and to overcome them and power was given him over all kindred’s, and tongues, and nations just as it was during the Babylonian Empire.
Daniel 7:24, 25 and another shall rise after them; and he shall be diverse from the first, He will think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time. The strength in Rome is that of deceit and evil heresies that Satan works through to destroy everything that God has already established in His timing and Laws. Jesus upheld the laws demanding that the spirit as well as the legal aspects of the laws be observed. Jesus did not come to destroy the law, but to fulfill the law, Matthew 5:17-20. The chief tendency of the priesthood was to keep the gospels away from people and keep them under the Roman religious doctrine as being the full authority as the rule of life and belief.
