Why can’t we keep battery stock at charging stations and replace the batteries in the car instead of waiting for the battery to charge? It would be much faster and many electric bikes and skateboards have this opportunity. I can understand that the current structure of the car might not allow but why is it not possible or if it is possible what is the issue being faced?

There have been companies that have tried this, like betterplace.
The reason it’s difficult is because manufacturers would have to agree on a standard battery format, batteries often have their own cooling system, which would have to be disconnected/connected, and anyone operating such a swapping station would have to have a stock of hundreds of thousands if not millions of dollars worth of batteries on hand.
It’s also a bit of a chicken and egg problem, because there’s no reason to build battery swapping stations if there are no compatible cars, and there’s no reason to build compatible cars if there are no battery swapping stations.
