Because they don't think about the consequences, and don't want to. Better to retreat into the emotional safety of techno-fantasy and feeling like you're on the cutting edge of something big and new (and might make some good money in the process). Same reason people got into NFTs.
This is a dangerous way of thinking about people who disagree with you, because once you decide somebody is stupid, it frees you from ever having to seriously weigh their positions again, which is a kind of stupidity all its own.
You just have made up an argument. There is no stated nor implied stupidity.
You can't dismiss critique of carelessness like that.
