I don't think self acceptance as applied to cis people in the context of beauty standards can be useful for alleviating dysphoria. Gender dysphoria is not just social and is not just a matter of not accepting yourself. Unfortunately there is no kind of "conversion therapy" that is successful in eliminating gender dysphoria - the only known effective treatment is social and medical transition.
There is evidence that surgeries that are used to pursue body ideals in patients with body dysmorphia do not alleviate the distress from the body dysmorphia, whereas surgeries that align people with gender dysphoria with their gender identity do actually reduce distress and improve well-being.
Gender dysphoria should be treated differently than merely an extension of beauty standards. Hormones do much more than just change how you look, they significantly alter your brain and mood. Cis people when forced to take cross-sex hormones develop depression and other mental health symptoms, and it's not surprising that many trans people likewise experience those symptoms and find they are alleviated upon having the correct sex hormones.
I think if you look closely at any industry you will find terribly harmful roots to those industries. To bake muffins you might use baking soda that was extracted from the earth in unsustainable ways that polluted streams, killed wildlife, and relied on exploitative labor practices.
You aren't responsible for the fact that medically necessary care for trans individuals like laser hair removal comes from or is connected to a cosmetics industry that has played a role in cultivating and exploiting body dysmorphia in mostly cis women.
The circumstances and industries don't have to be perfect to justify choosing to accept care that is proven to improve clinical outcomes in trans patients.
