And yet you have certainly used and enjoyed software published by others free of charge, and your employer, company or favorite service has relied on it. Your career may even be entirely dependent on it.

If you demand remuneration for all your work, then it's only fair for you to also pay for every single piece of software you ever use. If OTOH you're willing to trade some of your time and effort for the time and effort someone else spent on the software you enjoy for free, then you might appreciate that a financial transaction is not required for value to be created in the world. What is required is fair collaboration.
