He had a shop full of bottles of liquor. He sold some of them. He says he sold them to collectors who would hold them and maybe resell them, but not drink them, because that's what collectors do—and for that reason, he thinks he shouldn't have to have a liquor license?
For one thing, I predict a lot of that whiskey will end up being drunk anyway, even if the collectors did intend to "collect" it and not drink it, just like a lot of stamps from stamp collections end up being used as postage, and a lot of coins from coin collections end up being spent at their face value.
Sooner or later, most collectors of "collectibles" who hoped someday to sell their collections and get rich, wake up and realize that the stuff isn't worth any more than what they paid for it, and maybe a lot less.
At least with whiskey you CAN drink it. I can't imagine what people will do with all those Beanie Babies.
