In this imaginary world, does every house and business have it's own power station? Are small electronics powered by dc or ac? Do perhaps power strips incorporate something like a power supply that takes the long haul power and proivide something locally more usable, like how many power strips today incorporate usb power supplies? Is it worth making the grid slightly less efficient for houshold/office usage in trade for making it more efficient for EV charging at every parking spot, or is there something totally different like wireless power in the roads all along the roads...

You're asking how high is up.

Any simulation is an "imaginary world". Anyway, you clearly have no answers and add zero value to the conversation with your lame horse laugh fallacy responses. So, please, the next time someone asks a question out of curiosity (as the original commenter did), spare us your condescending and useless, zero value response.
