There is absolutely no justification, including any part of this. You can apply this argument to unregulated breathing.

The only reason people don't know what to do with any potentially dangerous thing is when they are artificially prevented from exposure and learning the appropriate common sense the same way they have to for everything else in the world like nail clippers. You don't eat them and you don't cut your actual finger off, because somewhere along the way you played with one or if you are particularly dimwitted, someone showed you and you memorized a rule. The danger of a phone is no differrent than the danger of any other computer, or a toaster oven, or fucking breathing outside of a padded cell.

This line of argument is exceedingly offensive and should be ridiculed without a hint of mercy or acknowledgement.
