Despite your hope, there is not even any inherent symbolism; gravity is simply a coincidence.
If I play an event that states something like this: put 1 influence each in 4 countries in Asia.
Is it impossible then for me to put influence in countries that are under my opponents control ?
Because when placing influence the first influence costs 2 when it is under the other players control
The extra cost applies only when the event specifies placing influence as operations points. If it simply says "place influence", you are unrestricted in terms of adjacency or existing influence in your placement (except by the event text, if applicable).
