Well, you can't keep stealing. Otherwise you become orange permanently and can't go into most towns. 

<<Area>> effect is an almost complete safe zone. The only thing bad thing that can happen is sleep PK.
There will probably be town areas where monsters can't enter, but orange players can.

If you want to continue pick pocketing, either have a guild with green players who co-operate or be the type of person to sell to orange/red players.
