This will never happen unless there is a substantial, and I mean *substantial*, payment for the use of an EV’s battery to top up the grid.
I don't entirely disagree with you.
However I would point out that much the same was said of solar panels. True, that hasn't "happened" in bulk. The point is that it has happened enough that the statement could not be held to be true of them. Indeed you can even buy shares in an investment trust hoping to profit from the roof space of industrial and commercial buildings. Presumably your concern about 2 way electricity has been solved for each solar panel installation.
Then again, it is not entirely unknown for some people to seek out options that they consider to have environmental benefits, without financial benefits. I believe that a number of electricity providers offer tariffs with the promise that the electricity comes entirely from renewable sources. Indeed some already offer special tariffs for those with an EV charger as well. ie

Would it be too far a stretch to imagine a V2G tariff in the future? Oh, sorry, this company does have one. (there are others)
https://www.ovoenergy.com/guides/demand-side-responseAs for a car with a range of in excess of 100 miles being left discharged before the work commute, it would be unlikely in the morning and if plugged in at work (work being on a V2G tariff), then surely the car can know the likely commute distance and ensure that it has enough energy. That is unless you tell it that you need it to have a full charge. Indeed it's likely that the car would even roughly know when you are likely to use it. Extra computing power? Now you are having a laugh. All modern cars are computers on wheels and some receive software updates via the phone network as you use them.
Why would someone leave an EV plugged in? During winter or summer when they want to get into a car with a comfortable temperature? No need to drain the battery before you drive. Indeed in some parts of the world they plug their petrol cars in overnight, either for the same reason or so that the car can start.

By the way, did you follow any of the previous links? The Ofgem one mentioned a possible payment of £725pa. I would agree that isn't substantial, but it might be significant. Especially were one to lease rather than own the car and hence battery. Others were large businesses who presumably are not doing it totally altruistically.
Finally, have you considered the possibility of regulation? The law now requires that a EV charger be fitted to any new house built. How large a stretch would it be for Ofgem, you know the author of the first link, to regulate on such chargers.
Never? Well you might be right.
