But why then traders doesn't simply read as "Zoner", instead of House Police/Navy? Also, Freeports between the houses are, as I wrote many times already, in an easily accessible region for traders (because, tradelanes). If traders can reach them, why the hell house authority bombers wouldn't do the same?
Then of course, I do realize what Spazzy said, as House Authorities would simply let the Freeports strive and don't bother to their "everyone are welcome" policy, out of pure grace.
