They probably couldn't figure out the legal part behind p2p in person crypto exchange but I didn't follow the crypto scene for the last few years so idk if there are any alternatives to localbitcoins.com

The most safe and private way would be to mine crypto coins and then spend them or exchange them for other crypto or digital currencies. Even Satoshi was pro exchange[0].
