Landing millions of soldiers somewhere is no trivial task.
You can just bomb from afar. You can also use ships. But why would anyone do that? Despite being easy, it's unnecessary. It would break down their economy and ruin some of its assets - knowledge, location and economy. That's why no one wages war anymore. It's not financially worth it.
Its about different mentality
In a country with 100 million people, that reasoning is not enough when you can compare 35 deaths against alleged 100K+ deaths. Either the major lethality is there or it isn't.
Multinationals would benefit from something like housing crisis 2.0 way more
Cheap labor and harvesting natural resources are way more important than income. When you hoard something like oil, you are holding something that cannot get replaced by any means. That's the greatest form of scarcety. Think of Splinterlands print limits, but in real life.
