If you're stupid enough to fly in IMC without a service of some sort, then that's probably true.
Are there still idiots around who put their trust in the 'big sky theory'?
If you read the statistics you will find some disturbing conclusions about mid-air collisions. Most of them actually occurs on a nice and sunny day in 10k+ visibility!
With this in mind, we are actually in more need of a Traffic Service in CAVOK than we are in 1.5K visibility or IMC. Sorry, but this is what the "big sky theory" is about.
