No, you’re missing the point again, when fish first went land diving they drank salt water because of that there body would have already had more salt and so would there kidneys, we evolved the ability to drink fresh water, that is what took a million years.
if humans would be adapted to that it could work but it would mean without modern technology it would be close to impossible to survive without access to saltwater (most of human habitable land area)
Well we were already adapted for it or at least our ancient ancient fish ancestors were we lost the ability that’s my core point, salt isn’t exactly rare and other minerals can be used to reduce osmotic pressure, but besides that 40% of all people live near salt water and ~30% of all land animals live near salt water so I wouldn’t think that would be enough to lose such a valuable resource as water, I am obviously wrong since we can’t drink salt water but it still feels like a miss step.
i guess in the case of humans we would have evolved for a long time to mainly eat fruit that has a high water content with low salt content possibly even being most of needed water intake. after starting to eat meat perhaps there hasnt been enough evolutionary pressure to be able to regain saltwater consumption ability
but whales like all sea creatures have high bodry salt content making the osmotic pressure difference small
Ok, so here’s an Idea, have more salt in our fluids.
Great idea except we’d need another million years of evolution or more

irradiated reproductive cells go brrr

Evolution is very short-sighted, and not at all good at planning.
