This is essentially what is considered the color-blind argument, which at face level makes a lot of sense. Let's just treat everybody the same and then there wouldn't be any problem. The issue with that though is that in a society/group where there has been some sort of segregation or bias, un less something is actively done to change that bias, it will remain on its own. It's a pretty pervasive effect, and it can be seen in sociological studies like this one. As you can see on that article, when all else is equal, black applicants with no criminal record, were called back 3% less often than white applicants with a record. There are many other stats like that, but the evidence all shows that society doesn't change unless we acknowledge these kinds of things.

If your work, good collaboration with others, and impact on an industry scale could all be taken equally across races, genders, sexualities, etc then you would be absolutely correct. Unfortunately this is not the case, and its going to take a lot of work for it to become the status quo.
