I think you might be missing something. Making art -some sorts more than others - simply requires equipment and stuff. I know this. I make art. I probably have more than some people because I work with different media: Watercolors, acrylics, ink, and so on. I'm prolific, and it all gets used. Just not all at once, you see.
This doesn't jive with the folks that brag about minimizing possessions - because it requires such. They might do digital art... maybe.
And rent a stocked studio? Most folks on earth aren't near such a thing nor is it something most folks can do. The few times I've seen any of this, you can't simply rent (and none have been near me). You have to apply to make sure you are good enough and do the right sort of art. At that point, you are representing the studio.
This goes for a lot of hobbies that requires a number of tools, supplies, and space, though. Simpy doing active work requires space and stuff - and some of it might go for months without use because you use different tools in different stages of work. (A woodworker might use a planer, but not every day and rarely if a piece takes a few months).
Actual, truthful minimalism accounts for this, but that wasn't what the topic in this thread was: It was the unobtainable minimalism that creates those that brag about having few possessions... and wind up having to rely on the labors of others to do sometimes basic things.
