Biden didn't think this up. His handlers did. There's no way a man who needs a map for a room could be thinking anything.

Reason? Typical leftist control freak-ism––we don't like it, so it must be banned for everybody? An attempt to look good like they care, so bring the full weight of the federal government down on something else people like to do (for your own good because you're too stupid to make good decisions)? The ongoing elimination of fun because the fun-sucking liberals in New York and California saw something that looked enjoyable, so, naturally, it must be eliminated in the whole country (for your own good because you aren't smart enough to choose things that are actually fun, like a liberal symposium on how to make people even more miserable and take their money or publicly screaming your bitterness against all the people they told you to hate)?

All of those things, yes, but probably because nicotine hinders their unnatural lab-created covid monster from infecting people. That is what the balance of probability suggests because they banned ivermectin and hydroxychloroquine, which are both extremely effective against covid.
