What about in DST, where caves are not available?

If 1 book can be read 5 times, then 15 tentacles can be spawned.

Each tentacle has a 20% chance of dropping tentacle spots, and only 1 is needed to make a new book. Going by strict probability, with at least 5 tentacles, one should be capable of dropping spots.

An average of 3 tentacle spots per book seems like the likely result. This means that each book when conjoined with the right odds, should lead to a profit of at least 2 spots.

At the very least... one is more then guaranteed, in which case, there is no real materialistic loss.

With those odds, I'd say that even without caves, tentacle spots remain renewable through player action. (Your sanity will suffer though. With all 5 readings, just one book will take your sanity to 0, no matter how much you had before starting.)
