Misdiagnosis are common when trying to get treated for almost any medical issue, because humans are not orderly, rational machines with well defined inputs and outputs. Gender issues are perhaps an easier one to look at and go "I'm pretty sure you got it wrong, doc" because you can look at someone and instinctively think "that's a man" or "that's a woman". But whether it's back pain that's actually caused by an incredibly rare knee cancer or a doctor misdiagnosing the cause of an ultimately harmless migraine, you run the risk of this any time you go to a physician. I've personally lost people I care about to misdiagnosis but it's still just a fact that I decide to accept: Physicians may try hard, but they're not perfect.
If a problem isn't severe, that might be a reason to avoid medical intervention so you don't take on that risk. But if you're really struggling to cope or it seems like you might have a serious problem, you should probably see a doctor. If their diagnosis makes you ask more questions, get a second opinion, or a third one!
Similarly, basically any surgery has the risk of complications, and lots of interventions we perform on a regular basis have a small but real risk of harm. It's something that comes with medicine, and overall, people live longer and happier lives because medicine usually works out. I postponed wisdom teeth extraction for years because the first dentist I saw about it put the fear of god into me about the terrifying risks of anesthesia, and ended up regretting it because they had to come out eventually anyway. But if I had been that rare statistic to die from anesthesia, maybe it would've been the right choice? I lean towards no, personally.
As far as blocking people from treating the root of the problem - while this is a real issue, if the secondary problem is seriously lowering someone's quality of life, there's something to be said for stopping the bleeding (so to speak) long enough to start working on everything else that's causing issues. It's a matter of triage - sometimes root causes simply cannot be dealt with fast enough to postpone dealing with everything else. A non-surgical gender intervention like blockers to get someone onto stable footing for a year or two could be a great step in order to refocus on everything else, and maybe at the end of that time they decide they don't need meds or surgery.
