Refueling a satellite in orbit presupposes that the satellite actually made it to orbit.
The flip side of amortizing the cost of the satellite over a longer mission is being able to cut your losses a bit in the event that the duration turns out to be 0.
I don't disagree but I also don't understand what you're trying to say here. All satellites are insured and if they don't make it into orbit the insurance claim reimburses the builder for the cost.
