I get the point you're trying to make, but to me this just reads like gatekeeping.
Cell phones are useful and they can make people safer. In a world with cell phones not having timely access to one is riskier. In a world without cell phones it's a moot point.
The more interesting issue -- which others in this thread are discussing -- is whether the benefits of having a cell phone outweigh the harms people can cause with them, and whether policy can help strike an appropriate balance.
