Trade in person is risky.

Trade in Bitcoin ATMs is expensive in fees for both buying and selling. In addition, Bitcoin ATMs will be regulated more, KYC requirements on users and Bitcoin ATM operators will be challenged by local governments.

I bet to differ that why we need to trade in person, trade with Bitcoin ATMs when we can have many options that can help our privacy as well as physical security.
Centralized exchanges are a lot, we can trade on them with fiat currencies, cards.
Decentralized exchanges, peer to peer marketplaces, without KYC, are available, why don't use them.
