When I said credit card I thought it was obvious I meant that debit cards are also acceptable. Turns out it wasn't!

Even if you include debit cards, you're still wrong.

You don't need anything. At all. According to Google, in case they suspect you might be lying about your age, they _might_ require age verification. This can be done with a credit card or an ID card.

So no, you don't need a credit card to watch age-restricted videos. You don't need a debit card either. You probably don't even need an ID card or anything at all.

You don't need to be of legal age to get a debit card, but you do for a credit card, hence why credit cards are often used as age verification.

Why do you think everybody lives in cities now?

Shouldn't be the onus on the regulator's part to prove that Google is selling or not protecting the user's IP address?

Google is an advertising network, they don't need to sell the IP to make money.

It's on the original website to prove that they only use your data for what you asked them to, if you want to do anything else, you need to request informed consent. Using hosted Google fonts is not needed to run the website (as you can also easily embed them without having the user touch Google). And Google will not say they won't do anything with that data, as they would be lying since that's the whole reason google fonts and other free webdev resources by Google exists: to gather as much data about the user it can.
