Unicode did not introduce having dozens of letters A, they existed without unicode. Unicode just gives you a way to represent them -- and bonus, often to normalize them all to a normal letter A too.

It is a mistake to think that Unicode has the ability to people's text behavior by not supporting things. I mean, maybe it does now that it's so popular, but in order to get adoption it had to support what people were actually doing.

People had use cases to put "𝔄" adn "A" in the same document and keep them distinct without unicode. It is not a service for unicode to refuse to let them; and if it tried, it would just lead to people finding a way to do it in a non-standardized or non-unicode-standardized way anyway, which still wouldn't help anyone.

You might just as well say "I don't understand why we need lowercase AND capital letters, the standard is just complicating things supporting both -- the ancient romans didn't need two cases after all"

There's no way to distinguish "A" "uppercase a" and "Α" "uppercase α" in written text, but they're different Unicode letters (and might be rendered differently depending on font).
