You seem to be of opinion that this is a simple situation with clear cut options one of which is always safe while the other can bring harm. That is not the case, as usual with problems that cause so much discussion on the internet. If the trans person is not able to get necessary treatment (which is well documented by medical professionals) it’s very likely they will experience depression and they may even suffer harm as a result. How can you evaluate that doing nothing in this situation may indeed bring less harm than another option? That is usually a decision that needs to be made by a medical professional, but what if that’s not possible? What if the doctors aren’t trained to deal with situations like this and would still bring harm by their choices?
