The wide-scale copying and distribution of the Scriptures is a benefit to our spiritual lives:
The law of Moses was wonderfully preserved by heavenly providence rather than by human effort. And although by priests’ negligence the law lay buried for a short time, after godly King Josiah found it [II Kings 22:8; cf. II Chron. 34:15], it continued to be read age after age. Indeed, Josiah did not put it forward as something unknown or new, but as something that had always been of common knowledge, the memory of which was then famous. The archetypal roll was committed to the Temple; a copy was made from it and designated for the royal archives [Deut. 17:18-19]. What had happened was merely this: the priests had ceased to publish the law itself according to the solemn custom, and the people themselves had also neglected the habit of reading it. Why is it that almost no age goes by in which its sanction is not confirmed and renewed? Was Moses unknown to those who were versed in David? But, to generalize concerning all sacred authors, it is absolutely certain that their writings passed down to posterity in but one way: from hand to hand.

Here’s the relevant quote from Deuteronomy 17:18-20:
When he has taken the throne of his kingdom, he shall have a copy of this law written for him in the presence of the levitical priests. 19It shall remain with him and he shall read in it all the days of his life, so that he may learn to fear the Lord his God, diligently observing all the words of this law and these statutes, 20neither exalting himself above other members of the community nor turning aside from the commandment, either to the right or to the left, so that he and his descendants may reign long over his kingdom in Israel.
Thank God that Moses didn’t copyright the Torah! Without an interest to copy, duplicate and distribute, the scroll Hilkiah found in 2 Kings 22 would have been worm food.
