Today, practically zero new indies make a living from selling digital copies of a thing they created. That income is eclipsed by giving away their main work, then asking for donations, maybe selling merchandise, early access, tailored commissions, or some other token (and sponsorships but those unfortunately hurt quality).

So abolish copyright, and indies still make money from creating digital works - at least almost as much as they do now, but probably more, because it will further normalize the alternate incomes.

Copyright maybe used to help indies, but every copyright case I’ve heard anywhere in the last decade, the plaintiff is a publisher with more than enough revenue. Meanwhile, in many cases the defendant hasn’t actually infringed, but regardless suffers from the DMCA, C&D, or lawsuit. Copyright relies on wishful thinking to provide an illusion of helping small-time creators, in reality far more often it hurts them.
