He made what he called "sensitive paper" for "photogenic drawing" by wetting a sheet of writing paper with a weak solution of ordinary table salt (sodium chloride), blotting and drying it, then brushing one side with a strong solution of silver nitrate.

So it was obsolete by the time the cards in question were produced AND it was nowhere near the, grab some ocean water and you're good to go process that you seem to think it was, but rather a measured solution of salt water. While that may be inexpensive it's not brainless.

How can salt water and silver nitrate be obsolete?

It would have been perfectly fine to use salt water and silver nitrate (or very diluted albumen and salt) instead of albumen and silver nitrate.
