I see, the blinding light. He sees a light and hears a voice, this isn't quite the same as meet in a physical sense.
Did Paul meet Jesus or not ?
If you are arbitrarily adding the criteria that he had to have physical contact, then you are contradicting Christ's teaching that He would manifest Himself (John 14:21).
Are you right and Jesus wrong here ?
Christ manifested Himself to Saul of Tarsus after His resurrection and in His exalted and glorified state. He did not promise He would only manifest Himself by means of physical touch. While this manifestation of Christ to Saul may not meet your criteria for genuineness, it met Christ's and God's.
Actually, after resurrection Christ was more interested that He would be manifested within those who believed in Him. So Paul emphasizes in Galatians, not how hard he fell on the ground, but that Christ was manifested IN him as well as TO him.
"But when it pleased God, who set me apart from my mother's womb and called me through His grace,
To reveal His Son in me ... " (Gal. 1:15,16a)
Maybe this does not match your priorities concerning the meeting of Jesus. But it does match the priorities of God. That is to impart the Son of God into people, revealing Himself to them and in them.
I'd go further. Jesus told the disciples that it was even expedient THEM
that HE go physically away that He might come to them, to live in them. He did not say it was to their disadvantage, as you insinuate. But rather it was to their advantage - expedient for them.
" But now I am going to Him who sent Me; and none of you asks Me, Where are you going?
But because I have spoken these things to you, sorrow has filled your heart.
But I tell you the truth, It is EXPEDIENT for you that I go away; for if I do not go away, the Comforter will not come to you; but if I go, I will send Him to you." (John 16:5-7)
You are saying Paul's meeting of Jesus was either second class or unfortunately inexpedient and secondhand. Christ says it is expedient
that He come to His believers in a form in which He could live in them.
