Of course I know that when you use it, it erodes away.
When the soap is new, packaged, never been used. It shrinks. Why does that happen?

Soap when it is manufactured sometimes contains voids or depressions. Soap, while a solid does have an amorphous nature and will change it's shape over time. Have you ever left a bar of soap in a hot area and returned at a later time to discover it's shape is deformed? Likewise, when soap is left in a cold area it could be expected to shrink.
Likewise, soap contains a variety of additives, perfumes and oils not to mention water which conspire to evaporate over time possibly leading to shrinkage within the package.
You should also consider if the soap in questin is aerated (containing small air bubbles). This could further affect shrinkage.

soap dissolves in water. it would be kind of pointless if it didn't, actually. soap molecules have a hydrophilic (water-loving) end and a hydrophobic (water-hating) end, so they can both dissolve in water and aid the dissolution of dirt and grease.

It is worn away.... chipped away..... washed away slowly as you lather it on stuff and allow water to run over it, kind of like a chlorine tablet in a pool.

Soap contains moisture / water. When it dries, it shrinks.

It gets used up.
