Yes, but even things like Bitcoin or Litecoin are much easier to use privately than bank cards. You can swap from Monero to them if Monero is not accepted, for example. You can buy them without KYC if you know where to look. With a bank card or something like Paypal, you'd need to use a "drop" (a random person to KYC your accounts) if you want anonymity, which is illegal so a normal person wouldn't risk it.

That said, while I use crypto for digital purchases like domains, I would rather use cash for physical ones. Or gift cards if available (where I am, they're almost-nonexistent and the only ones I've seen can only be bought with another bank card).
