I agree with you, but....
I hadn't stocked up with anything for the same reason you stated. But when Trump's announcement came out of left field? I thought it was pretty cheap insurance, so I got some nic. Not a lifetime supply, but enough for about 5 years. Which for me, using 14mg, about 2ml/day, only cost me about $60 for a half liter, and that was the costly premium packaged, argon filled Nude Armor. Thinking about ordering another for less than the cost of a couple of cartons of American Spirit. And now I've gotten a Solo, even though it's too big for me, and doesn't fit my pocket well. And I have a couple of different Pico's in my FT cart to add to only a few other external battery mods I have.
And then daily announcements from the various states. So I'm not really flipping out (yet), but learned the hard way when my favorite & coveted mods became no longer available (Nugget X, Macro DNA 75, Lost Vape Coral), that spending a couple hundred bucks now for piece of mind is worth it.
And for you on the nic? I don't know how your vapocolypse calculator works out, but getting a liter or two will not go to waste- someone here will be glad to take it off your hands. And buying soon could save you money, if there's real panic buying out there. Just the speed of this thing over the last few weeks amazes me, and I didn't think it was possible anymore for government to amaze me.
