A bit off-topic but to seal the subject: I know that Germany is quite different from most of the western world when it comes to online payment methods. I've read in multiple Hacker News and Reddit comments that most people there don't have credit cards, only debit cards (or that at least, those who have credit cards don't use them every day to pay for all stuff), that for online payment they tend to use their national solutions, and even things that seem a bit crazy like directly giving their online banking credentials to services so they can perform good old SEPA transfers. That probably makes using PayPal, which AFAIK deals mostly with credit cards, a bit hard to use. DarkestEx can probably confirm or deny what I'm saying but it's not really a PayPal or age thing, it's just the way things are done there.
