I don't understand your concern. I get what you're saying, but there a few things that just don't make sense.
Like why should an office building have charging at every spot? If you don't have enough juice to get to and from work, you need a current vehicle or place to live, or job. The days of 50 mile ranges are already behind us. A handful of charging spots at every building would add up, but no need for every single spot to charge, and no way they're all being used at the same time.
Do you stop and get fuel every single day? Then why would you need to charge every single day.
Cruise through any neighborhood, every 2 hours for a week. See just how many people are home at any given time. The thought of everyone in a neighborhood plugging in and charging at the same time every single day sounds like a super extreme edge case.
I get the grid concern, to a point, but I really don't think it's the problem you think it is.
It's a concern for the growing number of cities that are writing it into their energy code. It will be a requirement for new construction in these cities, and will likely roll over to existing properties doing improvements. Commutes in the area can get stupid long, we actually call them super commuters. Notice that the initial city pushing this is San Jose- which sees commuters from as far away as Sacramento. I never said every spot. They are requiring a specific percentage of parking spaces to have chargers, and a specific number more to be chargers ready- piped and capacity in the service. I don't have the numbers in front of me, but it's many times greater than what you see in parking lots today. If you install 2000A of EV charging, you need to have 2000A available. You can't just hope people don't plug in at the same time. The more people move to EV's, the more competition there will be for charging. What seems easy right now with less than 1% of the cars being EV, will change drastically when we hit higher percentages- especially once we pass the point that we can currently support. Home charging helps, to a point. That power has to come from somewhere, and it has to get to your house. The push away from traditional generation towards solar, and the move to overnight car charging creates a large delta between when the power is generated and when it is used. Hence the need for storage. Also, don't forget that as EV's are more readily adopted, it won't be small cars like most of the EV's currently on the market. They will be large SUV's and trucks, with bigger batteries.
The size of the battery isn't the biggest factor here, as the average person drives 31 miles per day and the new EVs can octuple that in real world capacity. As an EV owner, when I use local garages for a night on the town or for dinner with the wife, I do NOT use the chargers unless I actually need the power which happens....never. If I am traveling, and need a top up on the way, I use a level 3 charger which isn't what those garages will offer. If I'm traveling and have reacxhed my destination with low charge, I will use a level 2 destination charger. Mostly that will happen overnight at the hotel I picked because it has serveral level 2 chargers, or it might be in that parking garage. In that case, it will be empty of commuters and I will charge at one of the many spots the garage has provided me with overnight rates when consumption is lower.
I do this all the time....today. I have put 76k miles on my Tesla since May 2019. I rarely use superchargers even though they are free during my ownership of the car. Yes, the grid will need to improve, as it has done over the years already. Yes, batteries may need to be a part of that solution, but the good news is, storage batteries use less expensive materials (lfp,) are less finicky about charging levels, and are cheaper to produce!
Right now some commuters will plug in even if they don't need to, just for the free mileage. Long term, the solution will be idle fees which will have you move your car when its done charging. Idle fees will eliminate the vast majority of people looking for free electrons as they won't want to get hit with $1 per minute, or more, idle fees when done charging.
