More often than not, the methods are there to restrict access to the object's data, because there is some amount of bookkeeping to be done.
Esp true of ADTs, but also true of many other structs. A 3D transform, for instance, will sometimes have some bookkeeping for optimization.

the matrix is often calc'd as needed from position orientation and scale, but an internal mutable flag is used to prevent excessive calcs.

If anybody could willy nilly set that flag, it'd ruin the whole optimization.
