They're not concerned because no one is after them.
It's like asking, are you preparing for a North Korean missile strike? You could go out and build a blastproof bunker in your back 40, stocked with rations. You could setup early warning radar to know when to use said shelter. You could even move your entire life to that shelter so you'd always be ready.
The fact is, North Korea isn't gunning for you, so you're not really any safer than before you started. The boogeyman is in your head.
The vice cops aren't reading your texts and emails simply because there are plenty of idiots to mop their quotas with on backpage. They post a couple ads with maximum ~~~|||\~||\\\~|||~|~ and a low rate, setup a sting and rake in 30 guys at a time. This is simple, low cost, low effort and makes them look effective to the folks that expand their budget/salary/pensions.
Once in a blue moon, they'll go out and try to find someplace that's actually trafficking people and bust them. This is mostly for the publicity, not so much because they actually give two shits about it. They're really like every other government wage slave. They're just putting in their 20 years with as little work as possible, then retiring and collecting pension.
When you start framing things correctly they make more sense.
