In Germany there is a payment provider (viacash) that allows customers to pay in cash at selected retailers. You get a code, it gets scanned in the supermarket, you pay without any requirement for identification and get a confirmation. Big fan of that, but unfortunately only few websites are using it yet.
Oh OK. Changing model to pay per use is something we thought of but most people told us they would feel anxiety to search and preferred a fixed monthly fee. We are continuing to have an open discussion about this in Discord, our site and here on HN so lets see if we figure it out.
Prepaid doens't have to mean pay-per-use. It can mean I load up 50€ to my account and you debit 10€ per month until the account balance is less than 10€.

Posteo [1] also allows cash. But I'd say there that makes more sense than with Mullvad, because as a VPN provider they'll very likely know your IP address during operation, while for posteo you could at least access through tor (which doesn't make sense for Mullvad)
