I'm pretty sure the younger generation is intimidated by cash and think maybe only criminals and boomers use it? I am middle-aged and keep a couple of hundred dollars on me of petty cash for day to day activities. If someone “holds me up” it's not a lot, but it's great for keeping my day-to-day purchases anonymous. I'm all for making cash “an option” for every purchase or at least those under say $10k, not everything needs to be tracked or known.
