No, a wallet doesn't have to be digital. If you use a hardware wallet you connect it to a computer. Hardware wallets are great because you can put in the passphrase on the hardware wallet and not the computer which prevents keyloggers.

Also an ISP can't monitor where you are on a VPN, all they know is you are connected to a VPN server. If I sign up for a VPN account on one IP address and then use that VPN on a different computer and devices with a different IP address, then it's not easily tracked. If I'm connected to a server that has a lot of people connected to it, my traffic gets mixed in with theirs. If I convince many people around me to adopt the same practices and they convince others as well, pinpointing me gets even murkier.
