Many modern "mcmansions," which are often built by the dozens in high end
developments, now have 400 amp service.  This would allow for a continous
power of almost 77kW.

Not quite. That's the peak power available; not the average. The utilities aren't building out their network to supply that kind of continuous power level for every home. Only a fraction of that power is available for any length of time.

I'd guess that one nightmare scenario for the utilities is for everyone in the ritzy neighborhood to arrive home with their Teslas, and plug them all into their superchargers at the same time!
