This has happened to me while living and travelling in the Northern Triangle of Central America in the 2010s which at that time were the unsafest not-at-war countries of the world.

Depending on the time of the day and location I just ran errands with only the smallest amount of cash needed and an old phone. And sometimes I kept an emergency $1 bill to pay the bus in my socks . If I was robbed, the most they could get from me was the small cash I had on hand.

As money became electronic, organized crime changed tactics, and instead of only taking money from victims, they'd take the victims to ATMs to withdraw all their funds. Banks then reacted by limiting withdrawals at about $300 in ATMs depending on the risk of the area.

Yes this is one way it shows. Another is that there can be shops in your street that have no apparent viable business, but they exist only for the laundering. They are run by poor people. Every once in a while the real criminal (boss) shows up. It can cause all sorts of problems in good neighborhoods. Without cash, these problems would not exist.
