It's just a knee-jerk rationalization of conservative portion of our brains, fundamentally based on distrust in other people. I have my own story: These days many trans people are coming out, and sex change operation is becoming more socially acceptable. I was, for a moment, worried that trans people might be deciding on a whim/fashion to permanently alter themselves. But then I realized I miscounted - the number of people with gender dysphoria will always be greater than number of people unhappy with the change. So I changed my mind on this - it's always worth to change if someone really desires to. Ultimately, the idea that "other people will do it wrong" is a very anti-democratic sentiment.
