@Natanox The phrase "Copying is not theft" to me in itself does not mean that copying something and distributing it is always okay. (Neither does that phrase mean that theft is always bad.) For example, you shouldn't share a picture of someone, if they do not consent to it. But I find that copying and distributing someone else's creative work (art, music, software, whatever), or incorporating it into your own work is always OK, regardless of whether or not you pay them or credit them.
When it comes to "reaping the fruits of ones labor": people should be able to live their life regardless of what work they do or even if they do any work at all. What everyone gets should be needs-based, not based on how much they contribute. "From each according to their ability, to each according to their needs."
Now, I know this view is very idealistic and not in any way compatible with the inherent exploitative nature of capitalism and private property etc, which is the way society is currently set up. But even under capitalism, intellectual monopoly is not needed. Instead of a person or a company having a monopoly over a creative work and then essentially renting it out to make money, creative workers could be paid some amount for each thing they make, or, per month, regardless of how much work they produce. This is already used by "content creators" (I hate that term), where their supporters pay them monthly on services like Patreon, instead of the them "selling" or "renting" their videos.
