There isn't a complete picture here. In this particular case, Keffals shared that she was supporting alternate paths to get HRT, and providing support for folks who were legally blocked from receiving gender affirming care due to laws passed by a government largely captured by right wing politicians.
Given the complexity of pursuing HRT, it's not unreasonable to reach the conclusion that a child in those circumstances being denied care is largely related to a lack of parental support, or from being actively prevented from getting treatment that doctors were clearly providing (since the government had to ban medical treatment in order to stop it).
If the government bans some form of medical treatment and Keffals is trying to bypass this ban then this obviously would raise questions of legality.
