The concept of baptizing with the Holy spirit was known during John's time because John witnessed to them;
Mark 1:7And he began to proclaim: “After me will come One more powerful than I, the straps of whose sandals I am not worthy to stoop down and untie. 8Ibaptizeyouwith water,butHewill baptizeyouwiththe HolySpirit.”
John 1:29The next day John saw Jesus coming toward him and said, “Look, the Lamb of God, who takes away the sin of the world! 30This is the one I meant when I said, ‘A man who comes after me has surpassed me because he was before me.’ 31I myself did not know him, but the reason I came baptizing with water was that he might be revealed to Israel.”32Then John gave this testimony: “I saw the Spirit come down from heaven as a dove and remain on him.33And I myself did not know him, but the one who sent me to baptize with water told me, ‘The man on whom you see the Spirit come down and remain is the one who will baptize with the Holy Spirit.’ 34I have seen and I testify that this is God’s Chosen One.”
Acts 2:38Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit. 39The promise is for you and your children and for all who are far off—for all whom the Lord our God will call.”40With many other words he warned them; and he pleaded with them, “Save yourselves from this corrupt generation.” 41Those who accepted his message were baptized, and about three thousand were added to their number that day.
These people listened to the gospel and accepted it, they had a change of heart and were repentant- the result was that they received the Holy spirit and this is what we call baptism- from this passage, it is not right to insist that water was used.
It might be true that water baptism was common then but it was of no significance because even the disciples themselves and the apostles were not water baptized at any given moment yet they received the Holy spirit.

Also, if Jesus had been telling the disciples to go and spiritually baptize people, why would you spiritually baptize someone in the name of the Father, Son, and SPIRIT? I'm going to spiritually baptize you in the name of the Spirit?
