The point of the video is that you have alternatives if doing what you just said gets prohibitively expensive. Which is my case, my breaker box is diametrically opposed to the garage, but my dryer shares a wall with it. So sharing the dryer outlet is a great alternative. And 24A for my car would be more than enough.
I put in a 50A breaker and wired my 40A charger to it
