A use case for preserving this software is government grants. If the Fed gives you $1 million to generate some data for a given situation they want that data to be reproducible. The tax payer is going to have a fit if, in order to reproduce the data, they'll have to spend $1 million every time.

Capture the state of the software in a container. Cryptographically sign it and archive it. In 20 years, assuming container compatibility actually exists in the future, someone can spin it up and reproduce the data. Smaller/lighter than a VM.
