I see nothing wrong with that view, I certainly wouldn't disagree!
I see him as contrasting the things of God to the things of man.
For example when he says "for all flesh is a grass and all the glory of man as the flower of grass" he is referring to the temporal glory of man.
Then in vs. 25 he says "but the Word of the Lord endures forever."
This goes back to may original statement that he was expressing the contrast of being born-again not being of man which will perish, but being born-again of God through His word that teaches us salvation and endures forever.
I think we are saying the same thing in different ways.
actually brother he’s quoting prophecy from Isaiah about the gospel showing us it’s been fulfilled so Isaiah prophecies this of the gospel about 700 years before chrirts birth
“
The voice of him that crieth in the wilderness, Prepare ye the way of the Lord, make straight in the desert a highway for our God.
Every valley shall be exalted, and every mountain and hill shall be made low: and the crooked shall be made straight, and the rough places plain:
And the glory of the Lord shall be revealed, and all flesh shall see it together: for the mouth of the Lord hath spoken it.
The voice said, Cry. And he said, What shall I cry?
All flesh is grass, and all the goodliness thereof is as the flower of the field: The grass withereth, the flower fadeth: because the spirit of the Lord bloweth upon it: surely the people is grass. The grass withereth, the flower fadeth: but the word of our God shall stand for ever.
O Zion, that bringest good tidings, get thee up into the high mountain; O Jerusalem, that bringest good tidings, lift up thy voice with strength; lift it up, be not afraid;
say unto the cities of Judah, Behold your God! Behold, the Lord God will come with strong hand, and his arm shall rule for him: behold, his reward is with him, and his work before him.
He shall feed his flock like a shepherd: he shall
gather the lambs with his arm, and carry them in his bosom, and shall gently lead those that are with young.”
Isaiah 40:3-11
so Peter later is witnessing that Christ had come and fulfilled the prophecy and spoken the word of God that stands forever
“Being born again, not of corruptible seed, but of incorruptible,
by the word of God, which liveth and abideth for ever. For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away: But
the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.”
1 Peter 1:23-25 KJV
Then you think back to what Jesus had said
“Heaven and earth shall pass away, but my words shall not pass away.”
Matthew 24:35 KJV
and reflect on what Moses had said long before
“For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me;
him shall ye hear in all things whatsoever he shall say unto you. And it shall come to pass, that every soul, which will not hear that prophet, shall be destroyed from among the people.”
Acts 3:22-23 KJV
the Bible always works that way you have the prophets foretelling beforehand about Christ and the gospel then you have the gospel fulfilling those prophecies and then the epistles are witnessing of Christs kingdom and foretelling his second coming .
Peter and Paul’s doctrine and johns is always rooted in prophecy almost every time Peter was announcing that the prophecy of Gods eternal word being spoken had come and Christs words would stand forever
There’s a very cohesive message if we go from prophecy to the gospel to the epistles . Like a foundation and then a house built upon it the old is foretelling what came to pass in the gospel and the epistles are witnessing the truth of it and foretelling the second coming
Another short example of this
“But he
was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
All
we like sheep have gone astray; we have turned every one to his own way; and the Lord hath laid on him the iniquity of us all.”
Isaiah 53:5-6 KJV
That’s before the gospel and this is after
“Who
his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
For
ye were as sheep going astray; but are now returned unto the Shepherd and Bishop of your souls.”
1 Peter 2:24-25 KJV
God is telling us about Jesus all the way through in the ot it’s a prophetic word the gospel is fulfilling the ot prophetic word and the epistles are witnessing that it has come to Pass and foretelling more ahead regarding his return
revelation comes directly from what’s written beforehand for instance Paul’s message was always written beforehand he just began understanding it
“Having therefore obtained help of God, I continue unto this day, witnessing both to small and great,
saying none other things than those which the prophets and Moses did say should come:
That
Christ should suffer, and that he should be the first that should rise from the dead, and should shew light unto the people, and to the Gentiles.”
Acts 26:22-23 KJV
the Bible explains itself it’s one message being revealed slowly more and more through time until we see Jesus our Lord
