> You can get guns for that purpose for 80% less money.

AR-15s are by far the least expensive they've ever been right now, and are substantially less expensive than any reasonable alternative.

You can get a complete AR-15 for <$500, easily. If you're willing to put the parts together yourself, you can do it for ~$350.

You're certainly not going to get a new hunting rifle of similar quality for $70-$100.

Sure, they can be. It's a fairly common cliche that they're "Barbie dolls for grown men" - but I fail to see how that's relevant. The article was about preppers, not firearms enthusiasts.

Yes, but if you're not a subsistence hunter, and only planning to become one in unusual circumstances, the AR-15 is so popular that its parts and ammunition are widely available everywhere. In fact, I'd say an entry-level AR-15 at about $400 is a better choice for someone who isn't enthusiastic about guns, and doesn't want to expend too much brainpower maintaining them, as opposed to a $100 Cosmoline-encrusted Mosin or Norinco rifle. Even if it is overkill for hunting.
