It's an interesting question.
Again, remember this is my POV.
[Side note: It's possible that the unforgiving angel was Michael all along who we're later told is the principality of Israel in Daniel.]
I don't think it's the law - or the unforgiving angel delivering it - that obscures our view of the truth of God (or of the Messiah) like a veil. If I may, I think it's that "
our fleshly eyes obscure our view of the truth of God like a veil". Here's what I mean...
The Law = The Truth of God = The Messiah
Firstly, we know that while Moses was given "
the Law written in stone or letter", Messiah Himself
IS "
The Law made flesh" (or "the Word made flesh"). That's the only difference between the two versions otherwise they are one ...but the people faced the SAME PROBLEM with both versions causing BOTH VERSIONS to be broken;
their corrupt hearts and blindness:
- Moses shattered the tablets (because they couldn't SEE God and so made the golden calf to look upon, even calling it "Yah")
- Messiah's body was broken (because they couldn't SEE Him for who He really was/is and so mistreated Him)
Secondly, notice that even after the Messiah died on the cross, resurrected, and ascended to heaven to minister through the
New Covenant, unbelievers - even today - are STILL condemned by the Law (whether they're aware of the Law or not)...because only through belief in the Messiah does His death satisfy the Law for that person otherwise they're STILL under the Law's judgment.
So the comparison isn't so much:
OT Law (by angels) | God | Law of the Spirit (by messiah)
...Rather it's more so:
Mercy | God & His Law | Judgment
Life | Messiah | Death
Believer | Messiah | Unbeliever
(and one must go <<< through Messiah (as gate) <<< to get to the other side of it all)
The Almighty gave His judgment to the angel in the OT just like He gave His judgment to the Son in the NT.

So when WE SEE (and I'm just using "we" generally speaking) the law (whether in stone or on paper or whoever it's delivered through whether it's angels or even when Messiah is standing right in front of us ["
...this man gives us his flesh to eat???"
John 6:52]), we see it through
our unregenerate eyes. As
2 Corinthians 3 says "THEIR MINDS were blinded" and..."the veil is upon THEIR HEARTS". So it's not the law that causes obscurity it's people, people who only know this life through selfishness and death.
Recall that as the Almighty spoke His commands to the people at Mt. Sinai, the text reads as if the people were about to die
just by hearing His voice. It was too much for them to hear a Holy God speak His Laws to them (compare this to Abraham - their patriarch - who talked with God as a friend). So they pleaded with Moses to relay His word and for the Almighty to never speak to them directly again lest they die. The Almighty said they have spoken well, which suggests they really were about to die.
Let me emphasize: The Almighty was speaking His commands to them, so
The Law was initially given to the people
in The Spirit (not the letter) through
His Breath (i.e. The Holy Spirit)...and yet the people felt themselves
dying as they received it.
So the problem was and is with
people and their corrupt flesh and eyes. They were too corrupt to receive the truth of God's law (which is perfect love), and so it was veiled through intermediaries (like Moses and/or unforgiving angel) as well as veiled in written types & shadows and meticulous procedures...and even remained veiled in the body of Messiah until that Spirit was given to us.
