You seem to be posting a lot of "why doesn't Rust do things completely differently" posts lately. Please consider doing some preliminary research on such questions before bringing them to the forum, both to find answers and to find previous discussions on the same topics. In this case, this issue has been discussed extensively, dozens of times (see the link @RustyYato posted), and it is isn't even close to simple.
It's not that such questions are not up for discussion; on the contrary, they absolutely are. However, opening such a discussion needs substantial background research, a detailed post with context and awareness from previous discussions, a clear explanation of what's new since those discussions, and similar.
