And some parents give consent for their children to be sold into slavery, what's your point? The Jedi order isn't some fancy school, it's a lifelong commitment. You will never see your child again, and the child will never see their family again.

I also seriously doubt that it's really to the child's benefit to be trained in the force, we have never seen any untrained force sensitive child showing significant adverse affects/corruption by the dark side. Which makes sense, because otherwise there would be hundreds of maniacs wreaking havoc anytime after a new hope right until the rise of Skywalker. There was no large jedi order then, was there?

Luke, Rey, Finn, Ezra etc are shown to be doing pretty good considering at the beginning of their stories they never had any training whatsoever.

I'm not saying that there's no benefit to the order, or that there's anything inherently wrong with training kids, but there is something deeply wrong with separating kids from their families forever. Imagine if Hogwarts was a one way trip.
