Think about what you're saying. Anything can be made a felony, from murder to having a joint in your pocket.
Here in California, law abiding gunowners jumped through all the existing hoops to buy a certain legally manufactured firearm. A couple years ago they were told that those weapons had to be turned over to the state, or their mere possession would be a felony after the deadline.
The legal activity you enjoyed today, friend, could easily become the felony of tomorrow; will you have a problem with a law like this then?
