There is a lot to unpack in what you just shared, most of which is incorrect or incomplete. Unlike your theoretical idea of the Trans experience, I am a postop binary woman who is very aware on a personal level of the experience, the science, the options and the ramifications of being trans. I have three biological children. Addressing reproductive issues is part of the process of transition. I am perfectly happy with who I am and am passable. No one ever misgenders me. Physically, I am indistinguishable from a cis woman. At my first appointment with my gynecologist, she thought I was pregnant because my hormones are high. She could not tell the difference.
You misunderstand the purpose of therapy. For several decades now, the treatment of transgender people has involved input and counseling from psychologists or psychiatrists familiar with gender dysphoria. There are several reasons for this. One is to make sure that the person is in fact transgender and does not have some other psychological morbidity which mimics or complicates the condition. The second reason is to work through what is the most effective modality for ongoing treatment and to fully understand one’s identity. For many trans people, it is a process that is revealed over time rather than a single event of certainty. It is not uncommon for many trans women to start out thinking they are cross-dressers and not fully understand what is going on. It can take decades to fully accept who they are.
No physician that I know would proceed with life altering surgery without at least one expert letter supporting the decision. Historically under WPATH standards three have been required, two from mental health professionals and one from the endocrinologist providing hormone therapy, which is also a requirement. The proper approach and therapy modalities are far more settled than you seem to understand.
As to long-term risk of cancer and clotting, the risks seem to be reduced with the use of bio identical progesterone and estradiols. Most of the historical research suggesting increased risk was based on data regarding peri and postmenopausal cis women taking synthetic hormones derived from pregnant mare urine which have the risks you identify. The opposite appears to be true of the natural analogs. Your science is a little out of date.
But enough of this. The science and medicine is far more settled than you think it is. There have been over 4000 studies done which all conclude that the currently approved medical and surgical approaches are effective and appropriate. It is only the political environment and people’s emotional biases which create confusion. The scientists do not have the same doubts.
Does that mean that nothing will change in the future? Of course not. The nature of all science is for new things to be learned and existing ideas to be refined all the time. That does not mean that the current approach and understanding is inappropriate or experimental.
What is inappropriate is for those with no training and knowledge to suggest that things should be slowed down due to their own ignorance and gut instinct rather than letting those who understand what is really going on make the decisions. The rate of transition regret among those who have undergone life-changing procedures is less than 3% (some say less than one percent). This is an extremely high success rate for any kind of medical treatment.
