Rust's aliasing restrictions only apply to references. If you only stick to pointers and never at any point create a reference, you can alias to your heart's content.
For example, the equivalent[0] of the article's Offset Overlap example is perfectly valid according to Rust's abstract machine. What makes it hard is avoiding the creation of references. If I create a reference, then there's a good chance that the lifetimes don't get correctly linked up, and I accidentally have shared mutation/use after free/other UB.
