This is the centerpiece of their scheme - they want to be able to decide who is a firearms dealer retroactively, so they scan selectively prosecute individuals who sell guns. Presently, ATF's web site indicates that a number of conditions are required in order to obtain a FFL, many of which are related to actually being in business as a firearms dealer. I think that they have actively opposed licensing a lot of individuals in order to minimize the number of licensees. Because of course licensees have a broad range of things they can do, like ship firearms to other licensees, or buy firearms themselves without any new background check.
So now Obama wants it both ways - he refuses to set an easily knowable limit on activity which is not dealing in firearms, but wants to be able to tailor the definition to the desires of the moment.
Another reason to elect conservatives who will reject that kind of regulation as an affront to the rule of law. How can a citizen be expected to know if they are a firearms dealer or not if the government themselves can't define the boundary?
Hillary must be defeated.
