Correct. The law cannot be so exclusive (for example 500.00 registration) that it puts out the common folk. That is not a fair law.
That would be like making your drivers license fee 500.00. That would be outrageous for most people. And by the way, your car can be (and has been) used as a weapon as well!
But for real, My understanding is that the Madigan's cannot put up their too restrictive laws, cause they will get shot down and then there will be constitutional carry with no rules! So, in the end I think it will work out to be a pretty good carry law.
