Well said, although that's not the only thing at issue; the prominent tradeoff for that generally smaller (or less powerful) set of recourses is that you have easy, automatic memory management for the default case. I.e., you don't need to make decisions about how memory is managed unless you need to make those decisions. In C++ and Rust, you have to constantly make those decisions (which kind of pointer to use, where will it allocate, what happens to ownership, how will this affect callers, etc).
