There’s a fine line between not losing and refusing to acknowledge you lost to the point everyone gets tired of playing and you’re just the last man standing.
There would first have to be an actual argument in order to lose it. I have yet to read a valid argument. Language matters, pronunciation matters, names matter. The core concept of names is to identify people and to determine lineage, over time and regardless of location. In most countries you inherit your surname from your father. This is... wait for it... the same name. Not "almost" the same name or "close enough". The same. Whether you inherit your name from your father, your mother or both doesn't change the concept.
When you move from one country to another, your name nor its pronunciation changes. Subsequently your name also shouldn't change when you have children, because they inherit your name(s). And so on. Whether you, your children or your environment are incapable of pronouncing your own name does not change your name, it simply means it is being mispronounced. My accent, potential speech impediment or lack of interest do not change my name.
The fact that names aren't supposed to change further shows from its spelling which remains consistent throughout centuries. And no, lazy officials who are unwilling to type an accent or letter that is not on their keyboard by default are not an argument.
If names were supposed to change and don't really matter, then we would all be allowed to pick a surname for our children just like we pick a first name.
And while I agree that language evolves, that should not be an alibi to not even try and pronounce it to the best of our abilities and yes, some times that requires just a little bit of effort.
