I don’t get how your anecdote relates to SS7. SS7 is available country-wide (I’m assuming it doesn’t directly cross national borders) and the surface area of all of the cell towers and data centers they connect to is very large. Even larger if you consider all of the software that runs on the devices that are legitimately connected to that network. This isn’t even remotely comparable to some fictional high trust small rural town where everyone knows everyone.
I do have a lock on my mailbox, but it has to adhere to the USPS skeleton keys (which have been leaked and are exploited by thieves). Another example of bad design, or at least design that wasn’t able to withstand reasonably foreseeable changes to the operating environment.
