It's allocating resources towards preventing distribution. Maybe you'd agree that it's "direct" artificial scarcity, but believe without that necessary artificial scarcity we'd soon become worse off overall?
> I think the artist should have every right to profit from their work.
Sure - but you see that is not inherently the same thing as the specific method of profit extraction through requiring payment per access to the book/image/music/..., right? An artist receiving donations or public funding for releasing their work to everyone under a permissive license is still profiting from their work, for example. I'm not necessarily saying you have to agree that alternative methods are currently feasible in all or most scenarios.
