If you were an idiot, I wouldn't bother replying.
I've been a software engineer for more than two decades, and since 9/11, have spent most of my time on internet anti-abuse (both researching and writing code to fight it).
Privacy is one of my areas of genuine expertise.
Some of your (and others') concerns are legitimate.
Some are not.
Like most new technologies, it is important that people educate themselves about the real issues.
If you are serious about understanding this, you should take the time to read techie stuff, and avoid sensationalist treatments. Most (all?) of the mainstream media does not bother to spend the time to understand what they natter about.
You may have heard of "Cory Doctorow" (the "BoingBoing" guy).
I feel he often oversimplifies complex tech subjects, however, he is a very able science fiction writer, and did write an excellent novel titled "Little Brother", which will give you a much better gut feeling for how regular folks can fight back against some abuses. RFID devices feature prominently.
That will be a lot easier and more fun than wading thru dry techie stuff.
If you read it, post back, and we can discuss it in more detail.
That, too, will be more fun.
Warning: there's some heavy (often left-leaning) politics in it, which might bother some.
The tech stuff is solid.
If you want to counterbalance that with something more right leaning, the definitive computer revolution novel is Robert Heinlein's "The Moon is a Harsh Mistress". Despite being five decades old, it has stood the test of time. It's also my favorite novel of all time.
Im one of those persons that when surfing Y'tube and finds a posting showing another "NWO Concentration Camp" with someone commenting about the local train facility with security fencing, controlled access, cameras, big buildings, etc., I roll my eyes and shake my head. My cousin works for CSX and big trains require big buildings to do big repairs.
