I'm really curious what you mean by "privileged" for a person to be able to say "just shut your phone off".
I recently broke my phone and it took ~10 days to get a replacement. During this time, I had my wife text my family that I had no phone and wouldn't be responding to anything for a while. I felt no urgency, nobody got upset that they couldn't reach me, and thankfully there were no emergencies.
What level of privilege do you consider me having (or lack thereof that you apparently have) that doesn't let you do this? Genuine question btw, not trying to be facetious. I found the use of "privilege" here to be an interesting word choice and was hoping you could expand a bit.
