I don't think a DC layout with all the functionality of the of the devices
you are complaining about would have less wiring than a DCC. There would be
a LOT of wiring for a DC layout that had detection, signaling, transponding
(if even possible), enough cabs for many loco/consists (how many DCC
throttles do you have?), blocks small enough to allow for independent helper
operation (forget about independent double heading), automatic block
control, computer control..... Yeah, you can have a simple two cab/10 block
DC system with very little wire, but you can also have a simple DCC system
with even less wire. I think for a given amount to functionality/features
DCC will have less wiring than DC.
