Gaseous
I don’t savvy the bits about Brazilian tube and xxxx, if it was outside the area.
I guess we have to believe that you hadn’t a habit of over-flying / perving on Jack’s back yard and so the reason for the plod door-knock was as you say.
I agree that writing to any public servant can be exasperating, they may well be duty bound to respond to a letter but where is a rulebook that says how or when? Unless you have a 'tricky dicky' over there then the ombudsman may be an answer.
Perhaps you could have invited them in for a nice friendly cup of tea so they could see that there was no MPMG or rocket launcher behind the front door just waiting to be clipped to said Enstrom and invited them to use your phone to help verify the legalities of their assertions.
I had once the same problem, although the cup of tea invite wasn’t quite delivered with grace and came after a long and angry discourse; I was 2nm’s ouside a restricted area. It was something like;

Before they arrived, my wife had created a lovely snack of scones etc and had extracted –err forced—from me an admission that there were to be no smart arse comments about how our pilots can find their f’n way to any point on a wac map without radar, INS, gps or anything etc.
Understandably, she was most attentive during the morning pleasantries where we discussed the wx and everything - except - navigation.
I was coy enough to note (without comment again!) that they had a full S76 load of gents most with three or more shoulder bars and what looked like birds feathers all over their shirts.
I guess the S76 driver must have been real glad about having all those navigation trained blokes on board especially as the biggest feathered one of the lot sat up front with him to show him the way!
My wife must have been the smartest of all as guess what? I never had another prob with clearances.
