Logically analyzing the actions of human beings in terms of preferences, functions, and returns is hard. It’s not actually impossible, but pretty much everyone who tries misses important things that are hard to put into words. I’d first wonder why you think that birthday presents are supposed to be maximizing return in the first place.
Buying someone a present, for normal humans, requires both that the present not be too cheap and that some effort was taken to match the present specifically to the recipient. Maximizing return is not important. There are always edge cases, but in general, unless you are talking about an occasion where social customs require cash, cash is a bad gift because cash is not specifically matched to the recipient. It is very difficult to overturn this custom by just saying “I can use cash more than I can use clothes”.
Furthermore, parents are a special case because parents can make decisions that favor your welfare instead of your preferences, that would be arrogant if made by anyone else. If your mom and dad think that you need clothes, they’re going to buy you clothes even if you think you need something else more. There’s still a line beyond which even parents would be rude, but just deciding that you need clothes probably isn’t over that line.
It also depends on your age, whether you live with your parents (and thus they can see what clothes you own), etc. Also, did you even try to tell your parents that there was something you needed more than clothes, aside from cash?
