The biggest issue with saturation diving is not the pressure or the health impact, it's the fact that you share a tiny space with 3-6 other people for a month.
This might be the opposite of living in Alaska where you share a really huge amount of space with not a lot of other people.
That being said, there are not that many saturation divers, because being a month in a bubble is kind of least problem with it. The lifelong health impact is.
