It's quite difficult even for trained programmers to make their pipelines reproducibile. Just look at how much effort goes into build pipelines and the like. There isn't any good tooling for doing it so people build their own systems ad-hoc which they never document, that is if they use a system at all.

Big governments need to fund it and solve this problem once and for all. At the moment most grant procedures require something more concrete than just "solve the reproducibility problem", though.
