The rule has been you remove your own models. As with the other so called Chaos that I read in this new codex, I already see a quick FAQ coming out about other issues, the lash of crack is just another subject that will be expounded on.
In an established game area, you already have a repore with your group. There is a social norm that is already established, and this rule is depending on that norm. If with friends of like mind, you have a repore, just as you do a different one at a tourny, a new store, or a pick up game with a stranger. You follow what the rest of the groups does, or you quickly find a different one. Most of the time, I've found that the unsaid rule is " Move your own stuff". The several ocasions that I've seen a public display of picking up a strangers minis is in cases where Demo's, Scenario's, and specific games that are already prearranged, such as a Rogue Trader special event, ( The Hunt for the Fallen, Armaggedon, Cityfight, etc.)
I say let people touch your stuff, you better have a bottle of zap a gap at the ready. Not once have I seen a gaming group NOT have an issue with a broken arm, head, weapon, claw, wing, etc.
Glue is just like having a condom on the gaming scene. >
As for that " orderly chaos codex," this crap rule is just a stab at the randomness that the designers now discourage. It falls on hollow ears. Don't touch peoples stuff without permission.
