Maybe its possible to tie up npc monsters? with a smaller chance of escape.
Obviously different npc's will have different chances of successfully being tied up...

Although it will not give you the "Command" option but it will make good RP and even monster traps
Walk in a room and someone lets a dragon off the lead=not good
And even pet masters (Pets kept in rooms) selling pets to people
