Genuine question: why don't some trans people not want to be stealth?

Am not against it at all or anything, but I was just wondering why some trans people do not want to be stealth? Are you not afraid to always be known as 'that trans guy'? Doesnt that makes your life needlessly more difficult? I personally have been stealth since 15yo (Im 18 rn) and that has been one of the best things for my mental health. Isnt the point of transitioning to go through life as the sex/gender you feel like? At least it is for me. Again, I am not against it at all but I would like an answer to this question I've been wondering about this for a while and would like to hear ab your experiences 👍

Edit: Thank you all for your responses! This had been very insightful, it gave me new perspectives and helped me understand more.

And sorry about the mistake in the title loll english isnt my first language
