You can compare a 737 to 777 and if the 777 per person were 10x more expensive then airlines wouldnt use 777. Not sure why this is hard do unterstand.

Because things in space do not scale linearly, and sending 10x smaller sats is not the same as 1x 10 times larger sat. Some missions require larger fairing/lifting capacities.
