As I’ve already said, I’m not going to play the 20 Hypothetical and Theoretical Questions game. I think at this point the rule is established, as it has been for multiple months, and it’s been well-explained. The people who are subject to that rule (the 4 or 5 people who have been given the Separate Market Group exemption) were made aware of it when they agreed to do it.
The rule will be enforced according to its spirit. My advice (which I have already given to those folks directly) is that they proceed with an overabundance of caution and make sure it looks like nothing improper is going on, rather than trying to figure out the thinnest line they can find to not cross. At the end of the day if your goal is to spend all of your time playing with your existing friends or Fellowship in the Wilds, then owning a separate Market Group stall is probably not for you. Instead I suggest participating in your primary Fellowship’s stall, where these rules don’t apply. Or starting a new Fellowship with a small group of people you want to play with.
Again, I really don’t have anything else to say on the matter at this point.
