That's one point. Another is to reduce the burden of owning a car. In smaller towns where congestion isn't really an issue due to population size and low population density, efficient public transport is also difficult because you get minimal people using each individual route yet have to provide many underused routes to cover the area.

In that instance, ride hailing solves that problem by being point-to-point. It also means you're not sinking a significant sum of money into the ownership and maintenance of a car if you're only using it a couple of times a week, e.g.: for shopping and maybe going out somewhere on the weekend.
