Why did you and your rival steal your first Pokemon in Pokemon Diamond and Pearl?

So, if I remember correctly, at the beginning of D/P you steal your first Pokemon in order to protect yourself from Team Galactic. But why did Gamefreak make it this way? Pokemon is for children that are around 6-12. Wouldn’t Gamefreak at least once think “Maybe if we put this in our game foryoung childrenthey might steal too.” Is there a reason why Gamefreak put this part into the game instead of a more age appropriate scene?(that’s the best way I can word it)

First off, they didnt really steal them. Rowan and Dawn/Lucas left the breifcase there. You and your rival were curious and decided to go see what was in it. While looking you where attacked by wild Starly. You find pokeballs in the breifcase.Wouldnt you use those to defend yourself? Also after the battle, Dawn/Lucas comes back and takes the breifcase but leaves the Pokemon you and your rival used knowingly.

So they didnt steal them technically. They just used them for self defense and Rowan and Dawn/Lucas never bothered to take them back.
