It sounds like you are making an argument for penalizing future Crime, No reasonable person should find that to be ok and that is not whats going on here. You commit a felony you loose your 2nd amendment rights permanently end of story.
Now some may ask what is preventing government to lower the threshold of felony to speeding so it could disarm us all? and the answer is same thing that prevents them from just banning and confiscating all guns.
As pointed out by bc, there are MISDEMEANOR crimes that already carry with it forfeiture of the right to bear arms....scary precedent indeed....but hey it's in the name of public safety and predicting and preventing crimes that haven't happened based on fear.
