You CAN unplug if you want. True, it was better demarcated in the 90s, during the golden era of consumer modem-connected systems: you'd do your offline thing, then go to the PC, connect to your ISP, do that biz, then disconnect. But you can certainly emulate this with some personal discipline. Just a gentle reminder: with modern phones, you can control who can call you at 3AM using sleep mode + exception lists. It's pretty darn close to unplugging without the slim danger of being completely impossible to reach.
