you do not sacrifice memory safety. you sacrifice a compiler ensuring that code is memory safe by it enforcing one quite opinionated approach to it: RAII and lifetime analysis.
you seem to think there is one path to memory safety. there is not. unsurprisingly, some programmers may need different tools when working with a different set of requirements.
