> taking away a major monetization strategy (often the only viable one) massively reduces the incentive to create high-quality products and we all end up poorer for those cultural outputs not existing.

Ahahaha, to be quite honest I don't find that argument compelling at all. Profit motives seem to be making software much much worse, not better, compared to what I know is possible. I'm often finding myself reverse engineering/hacking things just to make them usable. From where I'm standing the current system is not doing a very good job. I can often make notable usability improvements in the systems I interact with and IP laws, the main driver of digital artificial scarcity generally prevent me from sharing them. I feel like I'm constantly fighting hostile software that's just trying to extract value from me in some way rather than actually solving my problems.
