…then we may never know for sure.
I tend to take the entire document as context and not just one sentence or one part of one sentence. When they say or show you can’t have 11 lights in your front yard (which have a function!!), or 8 lights on sunken pillars along the pathway in front of your base (which have a function!), and when they demonstrate for the sake of context the banning of people for having functional buildings (plural) in different areas of the map (which had a function) - then I have to consider that part of the whole thing as a single consideration. Not just the few words in the partial sentence. And I kind of hate to say it but not even the words in a paragraph - until such time as the language becomes precise and definite - omitting words and phrases like should, shouldn’t, I can’t see where, possibly, might, may, recommend, can often, too far, a large area, and so on… because often enough, their words aren’t matching their actions. Heck, even some of their own supplied images don’t match up. 
So yeah, we’re both wanting the same things here - an understanding of the rules. But without specific clarification on specifically maprooms, containing structure sizes, numbers of them per person, and so on there’s just no way I’m willing to say it’s fine when people are being banned for basically those same things - just not a specific case where maprooms were mentioned as the reason for the bans.
I mean you are of course free to assume that - but I wouldn’t! And if you’re reading this and you’re the type of person who cares a lot about your stuff, or about the humility of being banned from an online game then I wouldn’t even take any suggestions about any of them meanings from any of the people in this forum about maprooms being OK to place around the map, or anything else pertaining to the rules, the ToS, etc. without the specific comments from FC. “Yes/No, this specific item in this specific quantity, at this specific size, is allowed this specific distance outside of your immediate base.” etc…
