this is very naive.
life is not binary. maybe you can look better in a hair transplant until you are 40 (20-40 is when most men start a family, advance in career, party, etc) and when it's no longer manageable you shave it off.
Life happens in the very moment. So it's perfectly fine for someone to NOT want to shave their head right now, but throw in money and time into creating an illusion of hair through hair transplants and defer the act of shaving till it's completely necessary. That's when the question arises - "how does a shaved head look after FUE?"
Life is a journey, not a destination. It's not an equation where you say "oh if you are going to shave it at 40 anyway, you might as well do it now"
