Keep in mind that PayPal leaks lots of your personal information to the sellers, including full street address. Merchants don't even need to opt-in to get it, it's all provided by default for all purchases, even when there are no physical goods involved.

And yet 95% of all my purchases require a billing address, even if they we'll never ever send me a letter. Even better, some even check if the billing address is correct (they send it along with my CC# to my bank and my bank will decide what to do).

In Europe it's the law that you need to record the billing address (for 10 years) otherwise you can't obey the VAT laws.
