I think you're misunderstanding - most people's beef with AI art isn't that it "isn't made by experts", it's that

1) it's made from copyrighted works, and the original authors receive no credit; 2) it is (typically) low-effort; 3) there are numerous negative environmental effects of the AI industry in general; 4) there are numerous negative social effects of AI in general, and more specifically AI generated imagery is used a lot for spreading misinformation; 5) there are numerous negative economic effects of AI, and specifically with art, it means real human artists are being replaced by AI slop, which is of significantly lower quality than the equivalent human output. Also, instead of supporting multiple different artists, you're siphoning your money to a few billion dollar companies (this is terrible for the economy)

As a side note, if you have a business which truly cannot afford to pay any artists, there are a lot of cheaper, (sometimes free!) pre-paid art bundles that are much less morally dubious than AI. Plus, then you're not siphoning all of your cash to tech oligarchs.
