Wouldn't you also run into issues introducing a large amount of extra water to our ecosystem if we haul it back from the outer system? Water is infinitely recycled so adding more would change the weather, increase sea levels, etc.

Any science fiction where they can exploit a solar system and it talks about resources shortage, is generally idiotic. There is so much mass in the solor system, that its defacto infinite. Including water.

There is a classic science fiction novella by Isaac Asimov that kind of addresses this - spoilers ahead. Earth is concerned about the amount of water they are sending to support Mars colonists. Mars sends rockets and redirects a mostly ice moon to Earth, and says FU. !artisan Way

I mean truly running out of water is going to be very hard with the ocean sitting right there. We can desalinate water now. It’s just more expensive than pretty much every other way of getting it. The only thing more expensive would be gathering hydrogen from space and combining it with oxygen.

Also water doesn’t disappear. The water cycle recycles it. It all pretty much eventually hits the ocean. It isn’t getting ‘used up’, just getting less accessible.
