TSA afaik isn't even required for intrastate flights as intrastate travel isn't fed jurisdiction. In Alaska they don't even metal detect for weapons intrastate last time I flew.
If they're keeping TSA for intrastate flightd it's just as a fed funded voluntary jobs program for low IQ undereducated people to not have to rely on state welfare .
Your elitist commentary aside. The issue is probably more that at small Hawaii airports that have both service back to the mainland and inter-island flights, they just don't bother to separate the two pools of passengers.
I have done an inter-island flight from smaller small prop plane terminal in Kona adjacent to the main (but still small) terminal and I'm guessing I didn't have a security screening in that case.
