That's a pretty good argument. Why does the government have to pay for sex changes when it's not essential to serving the country? Will the government start paying for cosmetic surgery too just because I don't feel pretty enough? How about breast implants? Because we all know how important those are in serving the country. How about liposuction? In that case, sign me up! Feelings of fat folks like me can't be ignored! It's my right! Why does the homosexual community get special treatment and we fat folks don't? By the way, it's not my fault I'm fat. It's genetic,  

I've also heard from a friend of mine who's in the medical field that the maintenance after the sex change (check ups, medication, possible treatment for complications) is financially significant. Does the government have to pay for that too? Wait, I pay taxes, am I paying for people's sex changes? If someone wants to have a sex change, that's up to them, but I ain't paying for it! 

Welp, who cares. I'm only a tax payer.
