Tesla's batteries do not swap out in minutes, that is speculation on what they can do with some as-yet-undeveloped system. Patents and products are two very different things.
Yes, a car CAN charge a house, but where are you going to get the energy from? Your car is driven during the day and therefore relatively empty, thus requiring charging itself.
How about an update on that stadium project? Did it work. We're the results outstanding or disappointing? It's been 2 years there should have been some report on the result.
Your position is indeed based on speculation. If you have those convictions regarding batteries, might I suggest going out and making it happen? Actually prove me wrong, rather than talk about some hypothetical scenario where I could be shown to be wrong. Go start up a Powerwall competitor using used EV batteries or something to that effect. Being first in the door is sure to pay off when business gets big.

One of the big problems with energy usage on the grid is that there are peak times of use. This is problematic in several different ways. For one thing, the basics of supply and demand mean that energy prices fluctuate throughout the day, meaning a home or business who runs the AC and TV during 5pm will pay more than someone using the same power at 3am. Another problem is that the infrastructure for generating energy needs to be able to meet the peak demand, even though peak demand is not needed all the time. This is also expensive. Finally, energy produced from green technologies like solar or wind might have energy production mismatched with peak energy use.
The solution to all this is energy storage. Store energy when it is cheapest then use it from the batteries during peak times. This can allow a homeowner or business to save money. This plus solar can allow a home or a business to be off grid completely, and finally, energy storage can mitigate the holes in energy supply from the grid when green technologies aren't able to meet the demand.
Remember too that many businesses have generators to operate as power backups like the hospital that I work at has three generators, but a battery storage system could also be used during rolling blackouts or temporary outages.

Here is a video of a Tesla battery being unbolted in minutes. All of their cars have this feature.

My car is parked from 7a-730p in the hospital's parking garage every time I work, and it is parked right now in my garage since 10pm last night, so it could have been charging during none peak hours and used during peak hours. Compared to driving a car, operating the AC, TV and stove or whatever I'm using is going to barely dip into the cars battery storage.
The ideal home system is to have solar parking garages and solar homes, and at home, there is a small battery like a Tesla Powerwall, and the car can act as an additional bank if needed due to more demand or due to extended use during a power outages.
Recycled/repurposed car batteries will be ideal, and the cost will be pretty good. Here is an eBay ad with a used Tesla battery that is 85kW for $17k, and there are many more for sale. Just for reference, the Tesla Powerwall 1 and 2 are 6.4kW and 13.5kW at $3k and $6k, respectively. Someone would need 13 Powerwall 1s at $40k to equal the price of this used battery, and that would be a ridiculous amount of storage for one home for a daily use, but if someone wanted backup power or to live off grid then such a battery would be good.

Your update. It's on.
