People like to eat food and pay rent. Not everyone can afford to give away their hard work for free.
If you frame it that way, the problem isn't how can people charge for their passion, but how can we get people decent working conditions so that they can have a meaningful and rich life outside of work?
But knowing the internet, people will claim up and down that it doesn't have any value, while still using it. And then call the person greedy for wanting to feed their family.
Like Taylor Swift on Spotify.
> Something can have a value to me at free, and if the price were to rise at all, I would shift my consumption elsewhere.
And like I said, not everyone is lucky enough to where they can give away a lot of their labor.
