Locks and lockpicks

[Naamandre3]

This system would NOT be realistic, and the gains would be only to thieves. How realistic is it that impenetrable buildings should have chests inside them that can be broken into? Not really at all.

The lock system only benefits nomads, and even then they can be picked. In the end money is just wasted by everybody involved.

If I live under protection, who's to say that I can't keep my chests in a 3-block thick cobble room underground?
That's as realistic as any vault in the medieval era, it's only inconvenient.

Again. how would it not be? What impenetrable building back in the medieval/steampunk area was impentrable?
You are right that gain is to the thieves, and why shoudend they be? They do deserve an upgrade from totally impossible because of a single block over the chest. and that upgrade is to a lock that can be picked under hard cirumstances
