I agree. Sometimes the best you can do to cope with the sprawling ecosystems around programming languages and having to deal with convoluted codebases and inefficient programs, is sit down at home and building something simple (if you can spare the time and energy). That is what I do every now and then and it is incredibly satisfying to be able to explore how therapeutic programming can be when you are not boxed in.

I think this is not how companies work though, because they do not operate based on your views alone. And getting all people to agree on some of the topics you mentioned (e.g. importing dependencies vs. rolling your own implementations) is an incredibly complex task.
