I gave a myriad of reasonable suggestions, and you guys won't even discuss them. Your entire argument is the slippery slope fallacy. That's it. Arguing from emotion is a bad look.
Your three suggestions (far from a myriad) were:
1: National Firearms database
2: purchase tracking software
3: A nebulous and poorly stated ammo tracking and/or limitation.
Since you asked, let's break these three down.
1: The recent case of Hawaii medical marijuana patients is an excellent example as to why gun owners resist registries. You can be a law-abiding person today, and reclassified into a prohibited person tomorrow with little more than the stroke of a bureaucrats pen.
The Hawaii case isn't some slippery slope argument either, it's happening as we speak. To my understanding, it's being reviewed right now because of the massive president this would set.
2: I have the right to engage in private transactions with my private possessions.
3: As I told another poster in this thread, the idea of limiting ammo purchases falls under the category of punishing gun owners simply for owning guns. It's none of your concern, nor none of your business how much ammo anyone else owns.
I don't refuse your demands out of any emotional avarice, I refuse your demands because they're unreasonable.
