This may seem stupid, but where do you guys get plates from?
Not a stupid question at all. I can't speak for other users of the site, but myself I go to collector meetings all around the world, and exchange with other collectors online. Also I have got plates from registration offices in some countries, scrapyards, dealerships, "car boot sales", friend's old cars, and very rarely for me (but I know some people get very good luck) roadkill plates left on the streets. You can if you have a lot of money to spend buy them from ebay too, but I find that ebay is too expensive for most plates, way above the "market value" found at a collectors meeting for example.
If you are wanting to collect some, also be very aware there are a lot of fakes circulating the internet, some of them look quite good, so always find out if the plate should have security features or who is the official manufacturer (if applicable). Most collectors will be happy to give advice on this as most of us hate the fakes, although there are quite a few bad people who will try to sell or exchange a fake plate to a new collector

Correct, I wrote "EU" style because of the blue band, so it was clear which style I was talking about, and I see I didn't at any point write about the Muslim territories to make this clear.
