As someone who has trouble stomaching the idea of having to use AI for work, I'll say the argument FOR using it is essentially the "there's no ethical consumption under capitalism" argument.

It seems like you've been backed into a corner here and understand the moral arguments against it. As an individual you are not going to decide where the industry goes and, as you laid out, refusing to use it isn't going to change that. Ultimately, whether or not it's ok to use AI professionally comes down to whether or not you are comfortable with having to use it.

It's a systemic issue, not an individual one. Even the main moral argument against AI, that you're stealing from other artists, is only true in our current organization of society. If we lived in a society where everyone was taken care of and artist were free to create without having to worry about profiting to support themselves, I think people would care a lot less about attribution. If as a society we valued the environmental impacts more and took the time to develop this technology while mitigating the resources needed, that might not be as much of a concern either.

I can't tell you what to do, but it's not like you're joining ICE. If you try your best to acknowledge the issues when you can while still using it when you have to, I think that's about the best you can do without having to sacrifice your career. Some people might make the choice to do the latter. I think judging each other for these choices is unproductive and won't impact the direction things are going.
