If I have a liberal friend with an old timey guitar or piano with ivory and ebony keys, what federal hotline can I call to give them a taste of their own big government medicine?
I wouldn't wish it on the Devil himself but you could call the IRS use the name of said moonbat and tell them you have been deliberately under paying your taxes for the past 15 years and you can't live with yourself anymore. Set up a meeting for your friend, which he won't go to, and watch the government "medicine" in action.
Old-timey, they aren't in any trouble at all. Take ivory. You can still buy and own old guitars with ivory nuts and bridges; you can even buy a new guitar with a fossilized ivory nut and bridge. You just can't buy a new guitar with a new ivory nut and bridge. The same thing with pianos with ivory keys. You can own a piano with ivory and ebony keys. You could even buy a new piano with keys made of fossilized ivory. You just can't legally buy or own a new piano made with new ivory keys.
Or perhaps the best example, guitar-wise, is Brazilian Rosewood. It's the tonewood that was used for the sides and back of some of the most sought-after acoustic guitars in the world - pre-WWII Martins, like D-28s. Great sound, beautiful chocolate brown color with dramatic swirls of grain.
However, it became illegal to import Brazilian Rosewood into the U.S. after 1992 under CITES. You can still buy and own old Brazilian Rosewood guitars (and pay a half million on a really, really nice pre-war Martin D-28). Or you can still pay a fortune for new Brazilian Rosewood guitars - but the company needs extensive paperwork that shows the wood comes from a tree that was harvested before 1992.
But you can't buy or own a guitar made from Brazilian Rosewood harvested post-1992. It's like owning cowboy boots made from sea turtle.
