the parent said something about problems being solved if there was a standard library, and if perhaps there were a standard library people would be willing to write more code instead of just adding another dependency.

I believe these points

dependencies are carefully considered by users dependencies try to be dependency-free themselves to assist with the previous point dependencies solve important domain problems, they are not trivial one-line-functions dependencies are typically developed and tested by a known team or company, which you trust, not just someone random

would be solved by the parent comment's proposed standard library.
