Honestly, the Kingdoms probably don't want to stretch their defenses too thin because that's when the older, smarter Grimm (like the Goliaths) walk into their borders. Trying to defend every single inch of the entire continent that they're on would stretch their defensive resources really thin.

It's possible that mankind has pretty much settled on the idea that "There's no driving the Grimm to extinction. They just keep coming, and it's hard to research them, so screw it. Let's live our lives and protect ourselves when needed." I mean, they've been facing the Grimm for millennia.

That said, there could be some people who are searching for ways to eradicate the Grimm, but they're probably not too optimistic about it. The key may lie in defeating Salem, who 99.999999% of the world has no idea exists.
