Basically, the Jedi being actually pretty terrible is a big part of Anakin’s fall to the Dark Side, and if you want to enhance the themes of Qui-Gon being the only one who’s really got the right way of doing things, it helps to make it about “the Jedi won’t allow attachment so he can’t even check on his mum” instead of “Qui-Gon was fine with leaving his mother a slave if it meant getting a strong Force user for the Jedi.”
I really don’t like this aspect people attach to the prequels. I don’t think Lucas intended it at all. He genuinely believes in eastern philosophy and the concept of detachment from material things, including people, to become more spiritual, and that the Jedi are good guys. You could sincerely argue that the Jedi were right to not want to train Anakin and to teach him to let go, because it did lead him into trouble. (The only aspect that goes against this is the contradictory Chosen One stuff, which makes it seem like the purpose of his existence was to get in close with Palpatine so he could bring him down much later. But that’s another issue.)
In any case, I think it’s better to just remove the attachment ban/forbidden love stuff altogether. From the Lucas perspective it doesn’t play well to a modern western audience and comes across as cold, and from the revisionist perspective it takes away Anakin’s agency and responsibility for his actions. It makes it less a personal tragedy and more some kind of weird cautionary tale about the dangers of suppressing people’s Freudian urges or something.
