Earlier quoted context omitted.
“Copying” here refers to distribution and derivation, at least in the US. It is entirely legal to create copies of media for personal usage for instance (so long as you aren’t circumventing DRM, thanks DMCA).
This isn't correct. It is infringement, for example, to write Harry Potter fan fiction in private on a typewriter, even if another soul never sees it. Copyright includes creation, not just distribution
Copies for private use are going to be similar, and while I’m not a lawyer it feels like it’d be a hard case to make that work being conducted in private is going to have a meaningful impact on the market for Nancy Drew novels in the next 30 days.
