I see a hoary old chestnut here again.
I often fly IFR in Class G - when the vis or cloud isn't suitable for VFR. It's not "see and be seen", because you can't see a lot inside a cloud.
But how many accidents have there been (ever) in class G between any two flying machines flying in IFR/IMC?
Hint: you'll be a long time looking to find one.
