Not only are you overlooking the massive size and weight of these batteries which would make it infeasible to build a battery swapping station in a smaller footprint than the space required for charging stalls but you have not addressed what to do about the cooling of the batteries. The Model 3 has coolant lines going through the battery itself so each battery swap would also require dumping and refilling fluid. Nonsense.
