I think it depends on where you are more than your age. I very rarely carry a wallet on me and I am definitely not Gen Z. That being said, where I live, every legitimate (i.e. non laundering/tax dodging) business accepts paying by phone. I can use public transport by scanning my phone, I can prove my ID by showing my phone, I can claim medical benefits by using my phone, and every franchise has it's own loyalty app I can download on my phone.
If that's going on I promise you have much bigger concerns than how to pay for some mcnuggets. The same thing can happen to any credit card processor as well. Not a bad idea to keep some cash at home, but for day to day, hour to hour stuff there's no need to bring it anywhere.
No different from losing your wallet back in the day. Except I can log into my Google accounts on literally any Android phone (plus my yubikey) and get it all back.
Still, I will put a credit card in a different pocket sometimes when I am going out drinking just in case. If I'm really stranded I'll call the police from that bar, say my phone was stolen and beg them for a ride.
I don't have wallet, but I pay mostly with cash and carry social(student) card that works as public transport ticket and also works as state healthcare card.

Not sure why down votes, this is financial security 101. Some debit cards have gotten with the program but.... Still cringe. I do keep one on me but it's a free account I keep a bit of cash in, not where direct deposit goes to.
It's almost cult like, some people's "attachment" to debit cards. I've been called all sorts of things for pointing out how BAD it is to use them for everyday transactions.
Literally Home Depot is the only place left which doesn't have phone payments, and they really need to get with the fucking program. I wish more people would shame them for this.
Really need a first party app for credit card payments. I'm not going back to Google having control over my phone and you can't use GPay unless you let those scumbags watch you.
