Dried beans take more than that. You have to check over all of them to make sure they're safe to eat, because you don't get that guarantee as you do with canned ones. You also need to rinse them before soaking, although that isn't hard.

Stock would require having a lot of space to make it. We have only two burners, if we're using one up for a long time making stock, that's only one for actually cooking if someone is hungry, although I do have a crockpot. However, I do not regularly have materials from which to make stock. And when I do make stock, I generally have to buy fresh stuff to make it with, which somewhat defeats the savings part of it.
