my tutor friend probably has a temporary problem. as soon as remote school gets going, I'm sure she'll be able to convince her clients to pay for remote tutoring.

but as a social worker, you can end up making house calls to some very dysfunctional (or at least, the opposite of tech savvy people). a lot of these people simply can't figure out how to do video calls reliably; they might not even own a computer or have a mobile plan with enough data for video. sometimes the social worker is helping them perform physical tasks.

Face-to-face interaction is very important to both roles. You can certainly offload some, maybe most, academic instruction to online, but not the tutoring part.
