going to a bank is not anonymous..
Why not? Anyone can make a cash deposit. The teller is not likely to ask you for ID.
Nanaimo Gold offers several anonymous vectors for payment and some others that can be proxied by creative folk.
Also fully automatic trading of several hard currencies.
Nobody is ever asked for ID and you don't even have to make an account.
You don't even have to share your email address for most trades, and for those that do need it, you can use mailinator, jetable, tormail or other email anonymisers.
For anyone capable of lifting his ass from the chair, anywhere in the world, it's possible to buy bitcoin anonymously from Nanaimo Gold.
