I’ve seen it brought up before, the notion isn’t that it’s ethical or OK, but some people think that the draw post any of that stuff will be gone because anyone could do it and you’d never know if any of it was authentic. Kind of like if you flooded the market with lab grown rhino horns to crash the price and stop poaching, and then also the demand goes away because there’s no allure anymore.
I don’t know if Id bet on it, but it’s different than saying “I can deep fake porn of anyone without their consent so who wants revenge porn”.
