If you actually have shared ownership but in C++ you're getting away with pretending you don't, chances are that'll bite you really hard. Maybe it's already biting and you didn't notice, so Rust actually do you a massive favour.

If there is no shared ownership then inventing it so as to make your Rust slower is just a problem with you, not with Rust.

No. For 98% of the multi-core sensitive code I don't have nor I need shared ownership. While C++ doesn't force you into such semantics but provides you with the ability to do so, the Rust semantics and compiler pesimisstically do. I am going to stop here since I'm repeating myself and you're blatantly going over my points.
