The force drawing the weight and the mass of the earth 'under' it together (with the scale in the middle) however clearly exists as much as the electromagnetic force though.
Or stars, planets, etc. wouldn't (and couldn't) exist.
As to the exact details of how we account for it is another matter. Calling gravity 'measured spacetime curvature' or 'gravitational force', or coming up with pseudo particles, or whatever, is an accounting method. Either way, it's still there.
But it does clearly exist, as much as light (for example) does. All one needs to do to prove that is look out the window.
