It doesn’t really matter that software can be freely replicated when talking about means of production that already exist. Withholding them from other people when you are not actually using them with the purpose of extracting some sort of personal benefit is a net negative to society.

Ultimately, money isn’t a particularly good motivator (beyond preventing starvation and homelessness) for people to work on valuable projects for society. I think once you realize that and stop thinking about everything in terms of prices, it is easy to see how such a process could look like. But you need to take that first step to get rid of that capitalist brainworm yourself.
