So... just like the past few hundreds years then.

So is taking out the trash. But are you going to complain about the janitor who gets paid to do it?

Is it really so unnecessary? Moreover, is dealing with money ever not considered a security risk?

> Compared to not accepting cash and not having to deal with any of that, then yes it's a major burden.

Even not accepting cash is a security risk. Do you deal with your computer infrastructure? Card skimmers? What about cameras that take pictures of card information while being slid across the scanner? How do you deal with the security audits of the backend software? What about the background checks of the people who wrote the backend software?

You're falsely painting a rose garden. It's just a different garden, that's all.
