My Problem with Identity-bending Established Characters

I'm not an advocate of race/gender/sexual orientation-bending established characters. Mainly because it doesn't have a narrative affect on the characters or the overall story. There's a difference between changing characters' identity based on cosmetic decisions and changing characters' identity based on the decisions of the plot/story. The problem is most creative studios would change characters based on the former category. If a character's identify is changed for the sake of just changing said character then there's a possibility this decision won't make the character any better. An identity change of a character holds no baring if there's not any narrative reasons for it. If there's not a plot point that results a character going through dramatic changes that affects them throughout the story then these changes mean nothing. Or even worst, a character's identity is changed to the point of being a token stereotype.

Good example of identity-bending in a narrative fashion is a Netflix show called Altered Carbon where the concept of "stacks" and "sleeves" is established. Furthermore, it has established that people can place their stack (their consciousness) into different race, gender and age of sleeves (synthetic human bodies). Therefore, the identity change of  Takeshi Kovacs from Asian to white makes sense to the story. Rather than having the main protagonist being Asian in one episode then magically being a white guy in the next.      

Also I'm rather tired of people getting excited about how "progressive" these studios are all because they did a simple identity-bending on characters. You do realize that the reason they identity-bend characters is because... A. It's a lot cheaper for them to do than just create new characters/IPs. B. They don't wanna take risks of creating new characters/IPs. Or (optional) C. They're just really lazy to make new characters/IPs. Take points A and B, why else is there so many reboots/remakes in movies, comics and cartoons? Because it helps studios save money while making profit from reused IPs.
