Earlier quoted context omitted.

If you steal my book from the "Emergency Library" instead of buying an electronic copy, I get financially impacted.
This implies that "during the isolation period" modifies "harder to eat and pay rent" in a meaningful fashion. Restaurant workers are having a harder time paying rent.
Authors save for a privileged minority have traditionally struggled to pay rent as well but presumably no more than normally.
