Well some people do care, because some people may; have closer connections to these areas than you personally do. I am not against re-naming the Queen Charlottes, simply because relatively little has changed there since the arrival of Europeans and I believe half of the Island's small population is still Native.
And like wise, your argument that "absolutely nothing changes... we simply have a new name to use in specific contexts" can also be used against changing a place's name, since if a name does mean / change nothing, then why bother changing it? It is almost as if names do mean something to people, both Native and Non-Native.
(In all honesty, I believe that anyone who is born here is native to here, such as myself, I have no other home, this is the land I grew up in, this is the forest / wildlife I have known, studied and enjoyed, so don't tell me I have a lesser right / connection to it than anyone else. My family has been here since pre 1900, so I have no connections at all to the old world. The Natives as well originated from the Old World, and we all came from Africa, so really we are simply having a big family reunion in Vancouver
