$$, no problem...literally every bill we have CAN be paid online (most aren't as DH prefers mailing them in, lol).
Food we'd be good on, water fine as long as the city keeps it on (we think there is an old well but have to check ordinances on uncapping and blah, blah, blah) though we do have stored. Socialization...we don't ever see anyone on a regular basis except the nephew and his fiance so I believe we'll be alright. There would be a period of adjustment (i.e. straight jacket at some point for myself) if the net were to go but there are enough books around to entertain.
