By 'what' definintion?

You follow their instructions, therefore they are providing
separation. You can't see anything in IMC (the ostensible reason for
flying IFR), so how else are you going to maintain separation?

Most IFR flights are NOT in IMC.

If you see another a/c out the window, fine, but the idea of IFR is to
make flight safe even if you can't see anything out the window.

Wrong.
