Without knowing the particular bits of legislation or international agreements that you are referring to, I think we all could agree that it's unfortunate if human rights protections are eroded. Hopefully, that's an unintended consequence of various kinds of agreements, and hopefully those are the kinds of things that we can work towards remedying.
One of the things about rights is that they are not supposed to be balanced against well-being. They are supposed to more or less be absolute. The problem comes when protection of rights starts to have significant negative impacts, which it occasionally does, though not that often. The example that came up last summer was Victoria's Secret sourcing cotton from Burkina Faso and the use of child labour, in many cases where children didn't have any other options. So their options were either to harvest cotton or engage in prostitution or something worse.
