I tend to agree here.
Allowing a name change after initial creation might (and most probably would) end up allowing people to hide their previous career.
If their activities have been benign this might be of very little concern to other pilots but if they have indulged in nefarious and/or criminal activities (been a ganker, a corporate thief, a griefer, a con artist and so on) then this history ought to follow them and be something that other pilots can see and read about.
. . .
On a more general level, unlike real life (or at least as it extends to us as children) in Eve, you have the ability to choose your name. Up to a point you can choose any name you like and this can be (and more often than not I suspect is) reflective of the kind of pilot you aspire to be and/or the person that you are.
Like the paths of the Jedi and the Sith, you name can be reflective of light or it can be reflective of darkness. Either is a viable choice, but both come with consequences.
If you chose a name that is reflective of the dark side - eg: aggressive, warlike, ruthless, ambitious, cunning and Machiavellian - then it is possible that this is how you will be seen and perceived by others.
If you chose a name that is reflective of the light side - eg: peaceful, ethical, charitable, empathic, idealistic and trustworthy - then it is possible that this is how you will be seen and perceived by others.
Given the amount of time and energy you might invest into the game, the life lesson here is to choose your name very, very carefully and to be mindful of what impression the name might give off, both in terms of positivity and negativity.
