I think this is a thought-terminating cliche, and false equivalences. Stating "This area where problems occur at a high rate is not a problem, as problems can happen elsewhere too" is a curt dismissal of a valid concern. It implies the course of action, rather than to address a high-problem area, is to ignore any solutions which aren't global, or equate it to lower-incidence areas.

You bring up a good point that this class of problem, or related ones can occur with other package managers. It was frustrating how long it took the Crates.io team (Rust manager) to address name squatting, in what appeared to be a "no perfect solution exists, so we won't act" line of reasoning.
