Indeed, you're totally right about that. That's the trick with Mojo, our goal is not to make dynamic python magically fast. Yes, we are quite a bit faster at dynamic code (because we have compiler instead of an interpreter) but that isn't by relying on a 'sufficiently smart' compiler to remove the dynamism, it is just because "compilers" instead of "interpreters". The reason Mojo is way way faster than Python is because it give programmers control over static behavior and makes it super easy to adopt incrementally where it makes sense. The key payoff of this is that the compilation process is quite simple, there are no JITs required, you get predictable and controllable performance, and you still get dynamism where you ask for it. Mojo doesn't aim to magically make Python code faster with no work (though it does accidentally do that a little bit), Mojo gives you control so you can care about performance where you want to. 80/20 rule and all that. Mojo also has a more advanced ownership system than Rust or Swift, which is also pretty cool if you're into such things.
