I guess that depends on what you're talking about in terms of consent. If we're talking about medical treatments, the more serious the consequences of a treatment, the less likely it is that a court is going to say that a young person has the capacity. We can't really talk about capacity without also talking about what's at stake in either accepting or refusing treatment or asking for the intervention of the state to assist in suicide. The problem with a shifting age of capacity is this: Are we going to use courts to decide that?
I think it's much more important to have a firm age limit so we have a shared societal understanding of when and when not to allow access to MAID.
