The problem is that this is mostly done by people from privileged white background who can afford to give their work away for free and that puts into disadvantage people who simply cannot do that, because they need to pay bills and feed their families. For the same reason in many countries companies are not able to accept free labour, they have to pay at least a minimum wage for this reason as these spots would have been taken by people with rich parents "who want to find themselves" and poor people would miss out. This levels up the playing field. If you think deeper about this issue, you should be able to notice that this is somewhat a loophole around this legislation packaged into a nice and catchy marketing.
