obtaining a PPL is much too easy

Really? I'm a CFI and I can tell ya these aren't just given away

FAA is hopelessly conflicted in its roles

and flying with my GPS challenged buddy

One pilot's inability to to learn new equipment doesn't condemn the
whole flying population. That's a poor argument

how this most recent incident factors into the the ADIZ and GA airport security debate

It's strictly an airport security issue. The crew goofed by leaving the

ADIZ was violated. Even the TSA is saying that.
