Although I like all your arguments for Postrib, I'm not sure about a rebuilt temple. I know that Paul, in 2 Thes 2, states that the man of sin will take his seat in the temple of God, proclaiming himself God. I just don't know that Paul is referring to the temple as a symbolic posture, or as some kind of literal seating in a physical temple.
If this is a literal temple, what temple would that be? Paul knew the old temple of the Law was to be torn down and destroyed, along with the Law, forever. So in my view, Paul had to be saying that Antichrist would position himself like the false Christs, in the "inner rooms." (Matt 24.26)
It would either be temple Antichrist builds for himself, or simply a self-deifying claim to rule in God's temple in heaven. It certainly cannot be a restored temple of the Law! Just my opinion...
It will be the literal rebuilt third temple in Jerusalem.
2 Thessalonians 2:1-4 (MEV)
"Now, brothers, concerning the coming of our Lord Jesus Christ, and concerning our gathering together unto Him, we ask you not to let your mind be quickly shaken or be troubled, neither in spirit nor by word, nor by letter coming as though from us, as if the day of Christ is already here. Do not let anyone deceive you in any way. For that Day will not come unless a falling away comes first, and the man of sin is revealed, the son of destruction, who opposes and exalts himself above all that is called God or is worshipped, so that he sits as God in the temple of God, showing himself as God."
Matthew 24:15-21 (MEV)
"So when you see the ‘abomination of desolation,’ spoken of by Daniel the prophet, standing in the holy place (let the reader understand), then let those who are in Judea flee to the mountains. Let him who is on the housetop not go down to take anything out of his house. Let him who is in the field not return to take his clothes. Woe to those who are with child and to those who nurse in those days! Pray that your escape will not be in the winter or on the Sabbath. For then will be great tribulation, such as has not happened since the beginning of the world until now, no, nor ever shall be"
Revelation 11:1-3 (MEV)
"I was given a reed like a measuring rod. The angel stood, saying, "Rise and measure the temple of God and the altar, and those who worship in it. But exclude the court which is outside the temple, and do not measure it, for it has been given to the nations. They will trample on the Holy City for forty-two months. And I will give power to my two witnesses, and they will prophesy for one thousand two hundred and sixty days, clothed in sackcloth."
