Of course it's a good idea. It's like going back to the Gold standard. Only better because BTC is decentralized and it's easy enough to carry anywhere (portability) unlike the beloved "yellow metal". Mr. Kennedy Jr. knows there are a lot of crypto supporters in the US, so he needs their vote if he wants to gain an advantage over his rivals. After all, Bitcoin is the future of money. It cannot be ignored, whenever mainstream governments like it or not.
While the chances of Robert Kennedy Jr's election win are pretty slim, anything's possible. There are a lot of crypto industry players disappointed with the Biden administration's tough stance against crypto, so it's likely they'll vote for crypto-friendly presidential candidates. Who knows if the US will become extremely-friendly to crypto (especially Bitcoin) in the future? Just my opinion
