"A possible 100 [b]illion dollar industry seems like a very stupid thing to ignore." Even taking your optimistic numbers at face value, that's revenue, not profit. A 100 billion dollar industry with what I would conservatively estimate as having several trillion in costs is not something we can pursue. I've got my own boutique genetic problems in my house (not quite a one-off in effect, but probably technically novel), so I've got skin in the game, but this is just wishful thinking. Even just funding all the known rare diseases is not something we can really afford, let alone dedicating millions to every one-off mutation. We aren't that rich. I'm sympathetic to claims we ought to have enough for food and water and basic housing for everybody, but that does not translate into having enough to create custom bespoke medical research programs for everybody, or even a significant fraction of "everybody". If nothing else, food, water, and basic housing are widespread skills; fixing genetic errors would always bottleneck on the number of available people who can do it, which is never going to be as large as the number of people who can build some sort of house.
