I would say this is a case of Xenophobia, an irrational fear of strangers.

Xenophobia

People with xenophobia experience significant, sudden anxiety and distress when they are around strangers. They often go out of their way to avoid seeing, interacting with, or even thinking about strangers. This type of avoidance can negatively affect major aspects of day-to-day life. For example, someone with xenophobia may find it hard to function normally at work or in social situations.[3]

Dude in the picture is waiting.

I wouldn't do this, not because I'd be so worried about my life (because I'd pick a meet spot where any number of random people are that haven't stabbed me so far), but because once the price gets that low it's just not worth the time and effort to go through all the steps involved with setting up and executing a private sale. I'll just stick it in the box of things I'll donate so they hopefully are useful for a bit longer rather than end up in a landfill and someone needing to buy a new one instead.
