Phone locks are mostly a protection against accidental loss (self inflicted or stolen). But sometimes that's not worth the hassle. E.g. I disabled locks while my car was running. The tradeoff is IMHO well worth it as I immediately take the phone from the car should I leave. So the overall risk is minimal. Yet should it ever distract me then that's a big issue. And not being reachable was also not an option given family circumstances at that time. It's just a risk vs. benefit tradeoff. And that's a very personal judgment call.
