Making transactions outside any platforms will do. The OGs most likely escaped those digital footprints if they make deals outside like meeting someone willing tk buy coins at market price. This is also risky because we're also unsure who we met but definitely Cash is anonymous.
Such risk indeed exist, but it could be reduced with common precaution such as,
1. Meeting on public place.
2. Bring friend, family or someone else you trust.
3. Bring panic alarm/emergency button device.

Nobody is forcing you to use digital wallets for your fiat currency and bank accounts, you still have the option to choose cash, and p2p trading with bitcoin to cash is possible.
Depending on where you live, using cash isn't practical though since it's either hard to find someone else who willing to do that or faced worse exchange rate.
