I think the salt is actually worse for keeping thing cool longer.
Most of the cooling capacity of the ice is in phase change from solid to liquid. The salt is moving it to -10 which means bigger gap from outside temperature. So the cold escapes quicker.
If you use normal water it will climb to 0 faster, but stay there longer.
You’re wrong, look up old school ways of making ice cream. Ask an old person if they remember biting into a salt crystal when having old fashioned ice cream.
