I understand the federal fear, but didn't you have to register to begin with? Don't they already know? If you bail on taxes it could be really bad news...it might be the feds new way of "intimidating" people, or worse busting them.
i.e. dude gets busted says I have a liscense for that, the man says yeah but you are getting arrested for tax reasons not marijuana. If I was you I would pay it, nothing worse than some tax problems...just ask Capone
This also raise the question of do we want legalization or decriminalization? legalization requires the govt and rules is this really what we want? Or do we want a system that doesn't throw us in jail but rather fines us. I for one want no govt involvement at all, soon enough you will have to buy the govt's schwag or else....lets face it the govt can't run anything right, do you think they would get marijuana right?
