The borrow checker exists to force you to learn, rather than to let you skip learning. To make an analogy, I think it would be weird if I complained that I had to "memorize the rules" of the type checker rather than learning how to use types as intended.

Besides, if you still want to skip learning there are escape hatches like Rc<RefCell> but these hint pretty strongly (e.g. clones everywhere) that something might be wrong somewhere.
