Why of all the various practices of the Lotus Sutra, SGI's making available the writings of Nichiren Daishonin is of least value according to Nichiren

“The methods of shōju and shakubuku are also like this. When the correct teaching alone is propagated and there are no erroneous doctrines or misguided teachers, then one may enter the deep valleys and live in quiet contentment, devoting one’s time to reciting and copying the sutra and to the practice of meditation. This is like taking up a writing brush and inkstone when the world is at peace. But when there are provisional schools or slanderers of the correct teaching in the country, then it is time to set aside other matters and devote oneself to rebuking slander. This is like taking up weapons on the battlefield.

“Therefore, the Great Teacher Chang-an in his commentary on theNirvana Sutra states: ‘In past times the age was peaceful, and the Law spread throughout the country. At that time it was proper to observe the precepts and not to carry staves. But now the age is perilous, and the Law is overshadowed. Therefore, it is proper to carry staves and to disregard the precepts. If both past and present were perilous times, then it would be proper to carry staves in both periods. And if both past and present were peaceful times, then it would be proper to observe the precepts in both of them. You should let your choices be fitting and never adhere solely to one or the other.’ The meaning of this passage of commentary is perfectly clear.

“In past times the world was honest, people were upright, and there were no erroneous teachings or erroneous doctrines. Therefore, one could behave in a proper manner and carry out one’s religious practices peacefully and amicably. There was no need to take up staves and berate others, no occasion to attack erroneous teachings.

“As we have seen, it is said that one should let one’s choices be fitting and never adhere solely to one or the other. Therefore, we must look at the world today and consider whether ours is a country in which only the correct doctrine prevails, or a country in which erroneous doctrines flourish."

“But the present age is a defiled one. Because the minds of people are warped and twisted, and provisional teachings and slander alone abound, the correct teaching cannot prevail. In times like these, it is useless to practice the reading, reciting, and copying [of the Lotus Sutra] or to devote oneself to the methods and practices of meditation. One should practice only the shakubuku method of propagation, and if one has the capacity, use one’s influence and authority to destroy slander of the correct teaching, and one’s knowledge of the teachings to refute erroneous doctrines.

Of all the various practices of the Lotus Sutra, in this latter day, "copying" is by far the least important while shakubuku is the most important.
