Even something with no iteration at all takes time and money. Paint costs money. The time to sit down and write a first draft costs time.
Which, again, is where getting paid to create art comes into play. And peertube does not provide that. Which is especially bad in the case of video media as pretty much any youtuber will tell you: You are looking at at least a ten to one ratio of time spent creating/editing to any minute of footage. And that just goes up as you work on more complex works. A few of the “maker” youtubers are pretty open that they almost always have three or four active projects and a given 10-20 minute video might represent years of their lives.
