Touching something is part of the process of free will. Take away the touching and you take away the free will. God never said “you shall not go through the process of deciding whether to obey My command or not.”
The trouble is not the process of decision. The trouble comes when you actually hear the Word of God and choose to ignore or disobey it.
Genesis 3:1 Now the serpent was more crafty than any beast of the field which the Lord God had made. And he said to the woman, “Indeed, has God said, ‘You shall not eat from any tree of the garden’?”
vs 2 The woman said to the serpent, “From the fruit of the trees of the garden we may eat;
vs 3 but from the fruit of the tree which is in the middle of the garden, God has said, ‘You shall not eat from it or touch it, or you will die.’”
