I feel like I'm stretching the analogy beyond credulity here, but there's also a lock on the workshop and you can't leave it without finding a pair of bolt cutters.
I mean I do think the original article is an exaggeration (as is this analogy), and there are lots of tradeoffs to be made. E.g. in the Java ecosystem it's much easier to find a Spring Boot developer than someone who is willing to set up a project from scratch. Maybe that's a good thing for your project, but maybe it's not.
