I don't think it is silly at all. Not everyone realizes all these plans with RFID is out there. And everyone should be very upset that those making the laws are profiting from it.
The information is freely available; the fact is, like with GPS, people don't understand the technology and don't pay attention, until all of this stuff has been installed.
I don't think the problem is the technology.
IMHO, the real issue is the way in which the technology is allowed to be used - and who is allowed to use it.
I think it's a constitutional right to privacy issue that needs to be addressed.
