Yeah, I was being overly dismissive of your comment :) But beyond obvious hard differences in what languages in question allow about a given topic (of which indeed there are none between C/C++/Rust/Zig on the topic of memory utilization & co), everything is still just a skill issue. More seriously, afaict the article in no way even mentions RAII solving anything about resource constraints (not even as a hypothetical thing to disprove); only about RAII simplifying doing basic management logic (at the cost of worsening reasonability about resources!). Thinking about resource constraints is unquestionably harder than not thinking about them, which is what the article is about.
