I think I could probably manage entertainment without the internet, as you say normal Telly, radio and reading would be fine, although any kind of outing, theatre visit or even children's clubs are booked online.
Communication, as a family we use WhatsApp to video call more distant relatives, I suppose you would get back into the habit of actually talking on the phone.
Health, everything from our GP is through an online form.
Banking, local branches have been closed so it's through an app.
Paying bills, everything from utilities to council tax is online.
Even registering to vote is an online form.
I suppose you could visit the library ,or an internet cafe (do they even exist anymore?) and make use of the computers but their opening hours are being drastically cut, so,
No, I don't think I could manage without internet access at home.
