Why AI art is so controversial

I personally think it works as a tool, and perhaps for reference and inspiration,
and as artists, we should learn how to use it effectively,

however, I don't like that ppl can use it to take advantage of others (old dead famous ppl aside) apparently most ppl just take someone's art w/o permission to do so - like art theft w/o A.I isn't prevalent enough already...
and also presenting it as art, w/o labelling it as A.I, has some ethical problems imo

like, if you're using it for sth like idk, Wattpad, then I don't see much of a problem, it's just for a little visualisation (I haven't been there in a very long time, so idk what's changed the past several yrs)

but if you like, primarily use A.I art to make money in some way, I don't think that it's...for lack of better words in my brain atm (tired and hangry), fair.

There's always positives and a negatives,
but which side is heavier is usually always up for debate.
