@khsieh,
I would actually question how many people are doing _outbound_ geoblocking this extensively. It's not uncommon to have select locations (IE: China, Russia, etc.) blocked for outbound traffic, but it's fairly rare that I see anyone specifying outbound traffic to solely their own country.
I'm actually more surprised that you haven't run into issues with this extensively previously. Just in one environment I can take a quick glance and there's common resources from a lot of common resources that aren't processed locally in the United States.
Do you have any reason why you're being so restrictive with outbound traffic? Could you expand that to include common countries seen in your environment that could be deemed "friendly"? Just a brief glance and I'm seeing a large amount of traffic in just a single environment from places like Microsoft and Facebook being recorded outside of the United States, and I have to imagine that out of any country we likely have the most amount of 'local' resources being accessed versus someone living in any other country.
