Quite so.
To measure distances between towns/cities, some point is needed.
While in theory someone wishing to do so could query for the Admin level outline and compute the centroid, when a government entity has declared a named point to match the Admin level boundary, it's convenient if everyone uses the same one. If there are countries which for which open-licensed town centers aren't available, the local mapping communities can decide what is right for them. Postoffice, Town Hall, Centroid, Flagpole, whatever.

The centre of a place is a little cultural, a little of frequent use and a little from signs. In Europe I suspect it is the railway station ..lots of signs pointing there. In rural Australia I would go with the post office, though the pub is quite popular. :)
