Only read the title. Going by it: you could also kill me with a kitchen knife, your car, a bat (if you're fit), multiple types of poison, a homemade firebomb, etc.

The pearl clutching is just these folks out there who think, "if it wasn't for the laws people would be running amok murdering like the purge!"

These people are not to be taken seriously. "But what about" and "what if" are the most annoying things any person can say in a meeting to appear smart, and this is no different.

This is also why I'm building a cabin in the woods and I work for myself, but yeah.

> a bat (if you're fit)

Or if it has rabies.

The difference is the range of the delivery system. None of the options you mention allow you to remotely deliver a deadly payload without ever going particularly near the target location.
