When you correctly install and torque a wheel, the flush inner wheel face and outer hub face make for a contact patch that distributes the car's weight. The friction between the hub/spacer face and the inner wheel face is where the load is being taken. The wheel neither sits on the studs nor the hub/spacer lips.
This is a topic discussed ad-nauseum on other forums.
FWIW, my Z's factory lugnuts are tapered...

you got part of it correct but still not understanding the difference between these two wheel structures and where the loads are placed.
also your factory lug nuts have tapered tip because you are using standard lug-centric lugs readily available in the OEM market which have dual function.
some cars (toyota for instance and other nissans probably) use hubcentric wheels and regular steelie donuts. donut wheels are like a hybrid of both hubcentric and lug-centric design. they have universal lug bores so that they are compatible with both tapered and acorn nuts. (honda for example use acorn nuts on some of their cars). their center bore matches the hub diameter intended for the car to give it that hub-centric stability. basically steelies need to be cheap and universal.
so in summary, your stock universal hub-centric lugs have dual function yet you are only using one of the 2 functions.
