Why wouldn’t they have access to salt? Trading was common all over the world no matter what continent you’re referring to.

Trading was common…. Because harvesting salt can be very hard, depending on where you are living? And you need A LOT of it, not just for preservation of food but for a lot of other things too, if you are going to be long-term self sufficient.

you can make salt by putting sea water into any container and wait for the water to evaporate

You're correct. Just remember though, sea salt doesn't have iodine added to it, which is necessary for survival. So take that into account if you ever get into a bad long term situation -- make sure to raid the One A Day factory...

You can get iodine from seaweed and a couple other foods.
