>> Being a "creative worker" doesn't mean the market owes one a living.
Of course it doesn't. The starving artist trope is very much real.
Creative workers are mainly entrepreneurs, and they take massive risks for little reward. They work 15 hour days just like any startup owner.
>> Abolishing copyright would make competition and innovation easier, as well as allow creative people more freedom without fear of legal repercussions.
No it wouldn't. The flip side of copyright is that it prevents someone from going in a ripping up or destroying artwork without legal repercussions. This is why many street artists can become famous, which would be impossible if their work was simply painted over by the next artist. In many cities, the next building owner cannot even paint over it legally.
>> This would benefit consumers in the long run by driving costs down and forcing quality to win in the marketplace, rather than letting a few big companies assert control over valuable IPs.
You read the same internet as I do. Low quality work has won the content war through the shear force of quantity.
>> Many of us believe the right to freely edit and redistribute software is fundamental, why would that right not naturally extend to all forms of media?
Some creative workers believe the same, and there works of art of all forms that follow the open source philosophy.
However, there is a big difference between modifying (which is allowed under copyright laws) and outright theft. If someone clones your repo on github and takes full credit for your work, you wouldn't be happy about it. If they put ASCII dicks all through the source and said it was your work, this would probably offend you.
>>> Especially given that most creative output nowadays exists as software.
eyeroll -- most programmers aren't creative professionals or engineers.
