Select Outside Multiple Curves, Point Cloud

I've scoured the discussion board for a way to resolve this problem, but the solutions that have worked for other people (Con>Flip>Mass Addition) have not worked for this file. I basically need to select OUTSIDE of multiple circles, but when I try to do this with the containment component (setting it to "2"), it spits out ALL points. It will show me the points INSIDE the circles, and I'm wondering if there's a way to just select the inverse of those points? Rhino and grasshopper files attached.

Using Distance and not containment, so it checks if the points are outside the spheres with radius 1.5. Same reasoning if you want to use projected points and circles

(mass multiply {containment == 2}, flatten centers of circles, graft test points).

Do you really need to have these points 4000 kilometers away from the origin ?

Thank you!

The points are so far from the origin because they represent a real location in geographic coordinates. These coordinates are in UTM (instead of latitude and longitude). I need to keep them at their true geographic coordinates so I can later import them into a mapping program.

Thanks again!
